This beauty pageant is getting ugly.

Multiple sexual misconduct allegations are quickly amassing against former Miss USA vice president Max Sebrechts, husband to the national director of Miss USA and Miss Teen USA, Crystle Stewart, while the pageant is also being investigated over claims of “rigging.”

Sebrechts allegedly sent sexually explicit messages to multiple contestants, as seen in screenshots obtained by The Post. Some declare he’s looking for a “no strings attached” relationship and include a graphic video said to be of him pleasuring himself.

The Miss USA organization declined to comment to The Post about Sebrechts, but did, once again, deny claims of “rigging.” The rep also said that “Stewart and Sebrechts are separated” currently.

Miss Universe, the global competition that Miss USA winners go on to participate in, told The Post the organization was “made aware of the allegations against Max Sebrechts regarding his behavior towards 2021 Miss USA contestants” in December.

“Upon learning this, Miss Universe Organization conducted a review, which resulted in Max being completely removed from any affiliation with the Miss USA organization in January 2022,” the rep added. “Five months after he had been removed, in June 2022, Miss Universe Organization was made aware that Max had an extramarital relationship in 2018, in which graphic text messages and images were exchanged, two years before his wife, Crystle Stewart, was awarded the Miss USA license.”

At least four women received sexual advances from Sebrechts in 2021, one contestant alleged to The Post, while an anonymous whistleblower claimed “over eight” women had been “hit on” since 2008, when Stewart was crowned Miss USA joined the organization with husband Sebrechts.

““I’ve always wanted to at least tell you that I felt deeply attracted to you despite of my personal situation,” reads one email Sebrechts allegedly sent a contestant. “Maybe we could try [something] but def with no strings attached … And of course this is all between us, ok?” Later in the same email chain, he allegedly writes: “I was terribly attracted to your looks of course. Those tights you were wearing looked awfully sexy on your tight body.”

“I’m at the office right now I’ll send you a pic tonight,” he reportedly continued. “Unless I run to the restroom, the thought of imagining you in those tights without underwear has quite an effect on me.”

According to screenshots reviewed by The Post, numerous women allegedly received messages and advances from Sebrechts before he and Stewart “separated” that the receivers deemed inappropriate

Contestants reportedly filed complaints to Paula Shugart, the president of the Miss Universe Organization, and informed her of Sebrechts’ alleged behavior – and now claim they were reportedly met with inaction.

However, Miss Universe denied claims of inaction.

“Ms. Shugart was made aware of the allegations in December 2021 and upon learning of them, made the decision to insist on the removal of Mr. Sebrechts from Miss Brand,” the rep said. “Paula did act on the accusations, insisting on the removal of Max from Miss Brand and any affiliation with Miss USA.”

Mackenzie Kern, who held the Miss Wyoming state title in 2021, told The Post that the women “went to Paula,” but “they were ignored.”

“A lot of it was just disregarded,” said Kern — who claimed she did not personally receive messages from Sebrechts but contestants who did confided in her. “We were reaching out to people, we were reaching out for directors, and it was all brushed under the rug.”

Attempting to get the organization’s attention, an anonymous email blast was sent out in June from the pseudonym Mary Cunningham. Seen by The Post, the email included screenshots of flirty messages, sexually explicit emails and even a graphic video said to be of Sebrechts.

The email alleges that contestants were told, supposedly by Shugart, “not to repeat their experiences” and “advised to delete the sexually explicit texts by this married man” after coming to her for help in December 2021.

A pageant insider claimed to The Post that Shugart is “self-serving” and has no concern about the young women competing. “It’s no surprise that this was swept under the carpet,” they said.

The anonymous email from this June came six months after Shugart was supposedly notified of Sebrechts’ inappropriate advances.

The anonymous whistleblower who sent the email said the company reportedly knew of Sebrechts as a “sexual predator” and alleged it attempted to “cover up to protect him and his wife and colleagues.”

“It shouldn’t have come to light through a whistleblower. This was a missed opportunity,” Keith Lewis, a former Miss USA state director for California and New York, told The Post. “If you’re an organization that supports women, then why not walk the walk as well?”

The messages — said to be from 2016, 2018 and 2021 — reveal Sebrechts’ inappropriate communications with contestants, which were “unwarranted and unwanted,” according to the whistleblower. They claimed the messages put the young women “in positions of fear,” scared that they wouldn’t advance in the competition if they didn’t react positively to Sebrechts’ alleged advances.

“The age ranges of the people that he has attempted to communicate with are everywhere,” Kern, 22, said of Sebrechts’ behavior, citing concerns about his involvement in the Miss Teen USA competitions. “It just made me sick.”

Messages sent through social media show Sebrechts reportedly telling one contestant he missed her “good vibe” and sending her a photo he snapped of her and others in bikinis doing exercises. In another instance, he called a contestant “missie” numerous times and invited her to his hotel room “upstairs” to take in the “view” so he could “at least get a hug” before she left.

“I was under the impression that you looked at me as if you were going to eat me up like Godiva chocolate ice cream,” an alleged email to another contestant reads.

When the contestant asked about Stewart, Sebrechts allegedly said he loves his wife “more than anything” but was interested in pursuing an intimate relationship with “no strings attached.”

He concluded the alleged messages by saying he was “jumping in the shower” and adding a shirtless photograph.

The recipient of those messages, who claimed they met at the Miss Texas USA 2016 competition, told the Daily Mail anonymously that she and Sebrechts allegedly traded explicit photos, but that she regrets the interaction and feels that she was exploited.

She claimed she received messages from Sebrechts following her unsuccessful attempt at placing in the competition and noticing him “staring” at her the “whole week.”

“Around that time, I was very young and impressionable,” she said. “I think he knew the power he had in that position, especially considering that a lot of girls look up to Crystle and he used that.”

Another contestant recalled her own experience with Sebrechts to the Daily Mail, claiming the 42-year-old delivered a costume to her hotel room and kissed her on the “corner of the mouth” twice before leaving.

“I remember freezing in that moment. I knew that it was something that should not be happening,” the second anonymous contestant said, noting how “comfortable” Sebrechts was while behaving inappropriately and citing concerns for other women. “The only thing that was going on in my head was, ‘Are you stupid? You are not only the co-owner of this organization, you are married to Crystle Stewart.’ Crystle is an icon in the pageant world. She was my personal icon.”

At the national competition, Kern told The Post, she “vividly” remembers Sebrechts watching the contestants’ walking practices in the ballroom without Stewart present, which she claimed was unusual. “It’s usually girls-only energy,” she said.

“Being a woman in today’s society, you have a natural instinct of feeling uncomfortable around certain men,” Kern said of Sebrechts. “He would look at you, he would stare at you and watch you, and it was just weird.”

Sebrechts “shouldn’t have been anywhere where anyone was uncomfortable,” said Lewis, who was involved in pageants for nearly a decade. He said it’s a “failure” that the organization has not addressed the issue head-on.

“We listen to the stories of the women we’re around, we listen to the experiences they have, we shepherd them through difficult times, we’re well-versed in the difficulties of life in general and the difficulties of being a beautiful woman at different times, and being exploited or taken advantage of or being made uncomfortable,” Lewis continued. “I don’t think you can just hide behind this and say, ‘Well, we didn’t know what to do,’ or ‘We didn’t know how to act.’”

Kern called Sebrechts’ exit from the brand a “weak attempt” to remedy the situation. A letter sent internally to the 2021 titleholders, viewed by The Post, stated Sebrechts had resigned and that he would no longer be serving as the vice president of Miss USA, instead “focusing his efforts on other business ventures.”

“This should not have happened on [Shugart’s] watch,” said Lewis, who left the organization in 2013. “Women don’t allow things like this to happen to other women.”

Miss USA came under a microscope early this month after the annual competition when contestants claimed the pageant was “rigged” in favor of Miss Texas, R’Bonney Gabriel. State titleholders flocked to social media to share their criticism of the contest, saying the Miss USA brand showed “favoritism” toward Gabriel, which it denied.

Miss Universe told The Post that an internal investigation would be conducted, which Miss USA would be compliant in.

“The current allegations that the 2022 Miss USA pageant was in favor of one contestant over another are misleading and simply not factual,” Stewart, 41, told The Post in an emailed statement. “I am fully cooperating with the open investigation being conducted by a third party at the request of the Miss Universe Organization. I am eager for all of the claims to be disproven and the facts will speak for themselves; ultimately, putting all contestant’s [sic] minds at ease once and for all that this was indeed a fair pageant. As a former title-holder, I know first-hand how much hard work, mental preparation and dedication goes into the process of being on the main stage. The last thing I would ever want to do is discredit or deny the contestants an equal opportunity to a fair competition. I would never jeopardize my dream of running an organization that empowers these young women.”

Miss Montana 2022, Heather O’Keefe, one of the whistleblowers who claimed this year’s Miss USA contest was “rigged,” revealed via TikTok that Miss USA has been “suspended” and that Miss Universe “will be taking [it] over” while the parent company investigates the national competition, which the Daily Mail also reported Thursday.

Kern told The Post that Stewart was someone she looked up to as a role model, and while she understands the driector wants to “protect her brand and her image,” she’s “disappointed” that her “moral compass” was “off.”

Lewis said allegations must be taken “seriously,” especially since pageants are meant to “empower women and their voices.”

“We have to make sure that we are always putting them in positions where they’re going to prosper,” he said, “and certainly never in positions that could endanger them.”
