What is this feeling?

Fans were left stunned after Kelly Ripa transformed into Ariana Grande from “Wicked.” During an Oscar-themed episode of “Live With Kelly and Mark,” the talk show host, 54, donned an identical outfit to that of Grande’s Glinda the Good Witch.

Ripa wore a pink dress, gray hat and matching pink purse in an Instagram photo shared by celebrity makeup artist Kristofer Buckle. The “All My Children” alum pursed her lips together, striking the same pose the singer, 31, normally does in pictures.

Ripa also posted behind-the-scenes footage, showing a Timelapse video of herself transforming into character.

“Follow me beyond Oz into the land of make believe,” she captioned her Instagram post. “Let’s hear it for the actual wizards. @kristoferbuckle@ryantrygstadhair#AfrertheOscars.”

Ripa sat in a makeup chair as they re-created Grande’s makeup look and did a photoshoot in front of a green screen, mimicking looks and scenes from “Wicked.”

“Omg you are the perfect Glinda!!!” one person wrote in the comments section, while a second social media user shared, “You are incredible Kelly! You can morph yourself into anybody and look exactly like that person!!!”

But the transformation wasn’t as popular with other followers.

“Oh my word! That is quite scary,” one critic said, while another agreed, “this is terrifying.”

“That’s creepy,” said a third follower.

The creeped out social media users continued to voice their opinions, as one added, “The girls keep transforming into Ariana like it’s getting SCARY out here.”

Some even had a suggestion for the star’s next appearance: “Now do modern day Pamela Anderson!”

Ripa’s husband and co-host, Mark Consuelos, 53, also underwent a “Wicked” transformation, playing Jonathan Bailey’s Fiyero on the morning show segment. But his wife actually had him thinking she was Grande at first glance.

“I was like, ‘What!? I’m not prepared for this,’ ” Consuelos told People. “And she completely fooled me because when I grabbed the phone, I truly thought that was Grande.”

“It was very funny because I could see he was secretly annoyed and doing that fake nice thing at first. He was like, ‘Oh my gosh, hiiiii!.’ And then once I spoke, his face totally changed and he was like, ‘Wait a minute…’ ” Ripa told the outlet.

Consuelos teased, “It was freaky!”

Ripa also gave a scare to her and Consuelos’ daughter Lola, 23.

“I FaceTime’d my daughter and her best friend while I was in costume and fooled both of them, too,” she said. “It was great.”
