Ivana Trump, the glamorous businesswoman and ex-wife of former President Donald Trump, was remembered as “a force of nature” and “the embodiment of the American dream” at her funeral in Manhattan Wednesday.

“She had brains; she had beauty,” her son Eric Trump said in a speech at the historic St. Vincent Ferrer Catholic Church on the Upper East Side. 

“She was the embodiment of the American dream … She was a force of nature,” he told mourners.

His mom, a former model and onetime professional skier, “could beat any man down the slopes, any woman on the runway.”

“She ruled the three of us [kids] with an iron fist but also a heart of gold,” Eric said of himself and siblings Ivanka and Donald Jr.

Donald Trump, wife Melania and their son, Barron, sat solemnly in the first row at the private service to honor the famous, Czech-born New Yorker. Don Jr. was also in attendance, and his teenage daughter Kai Trump gave a speech remembering her beloved grandmother.

Eric’s wife, Lara Trump, addressed the mourners as well, as did Ivanka Trump, who attended alongside husband Jared Kushner. Tiffany Trump was spotted inside the church, too.

In an emotional speech, Ivanka Trump described her mom as a tough-as-nails trailblazer in the business world.

“Growing up, my mother didn’t tell me a woman could do anything she wanted to — she showed me,” she said, holding back tears. “She was a trailblazer by men and women alike.”

“My mother once told me there was nothing she couldn’t do in heels,” she said. “She taught us how to spear fish and then cook what we caught.”

She added, “My mom expanded our minds.”

Clad in a navy blue suit, the ex-commander-in-chief arrived at the Upper East Side house of worship amid tight security, as dozens of mourners gathered on a sidewalk outside to pay respects to the 73-year-old “power blonde,” who died from a fall last week.

Roughly 100 mourners sat inside the church, which was decorated with red roses and candles  in honor of Ivana, ex-wife of Donald and mother to three of his five children. At the front of the Gothic-style church were two blown-up, gold-framed images of Ivana — including one of her gracing the cover of Vanity Fair.

The invitation-only funeral was billed as a “Celebration of Life,” with the invite featuring a photo of Ivana on the slopes.

Don Jr. called this mom “fearless and independent” for “escaping the Iron Curtain” of the then-Communist Czech Republic.

“[She] shattered so many norms,” he said, describing her as industrious-meets-glamorous.

The day after her divorce with Donald, she marched into the Plaza hotel and got back to work, he said. Ivana could command a boardroom —  then make a “group of construction workers blush,” he said.

Eric Trump said his mother remained youthful until the end, despite her recent health issues.

“Don’t ever call her Grandma … that just wasn’t her thing,” he said, adding that his kids called her “Ivanma.” 

 “The night before she passed, she told me she was going to live to 120 years old,” he said.

Don Jr., Eric and Ivanka, the three children the former president had with Ivana, sat in the front of the church with their dad, who did not speak at the funeral.

Grandaughter Kai gave a heartfelt reading, then broke down in tears, describing how she’ll miss her grandmother, and bemoaning that they’ll never be able to travel together to the Czech Republic.

Before her death, Ivana — whose headline-grabbing marriage to the real estate tycoon whom she famously dubbed “The Donald” established them as a 1980s New York power couple — had been unsteady walking in recent weeks due to an ailing hip, friends had told The Post.

She suffered “blunt impact injuries” due to her fall and her death was ruled an accident by the Medical Examiner’s Office.

It wasn’t immediately clear where Ivana will be buried.
