Many celebs have taken to social media to give a glimpse of what they could look like in a few decades through FaceApp, an iOS and Android mobile app that applies faux-aging filters to photos.

But as far as pop icon Carey is concerned, the app, which shows users what they look like with wrinkles, gray hair and sagging skin, does not exist. 

"FaceApp is not something I acknowledge," she wrote on Twitter. Carey also attached a GIF of herself in an interview captioned "I don't hear you, I don't see you, You don't exist to me."

Although Carey has said she's going to sit out on the latest viral trend, other celebs have embraced the app on social media.

Brody Jenner shared a photo with Clint Eastwood, joking they were enjoying a senior discount.

"Clint and I out for the early bird special at Golden Corral," he wrote on Instagram. "Come through for the bomb split pea soup..."

James Marsden also got in on the craze on Instagram.

"Sorry it’s been a while since I last posted," he wrote.

"To All the Boys I've Loved Before" actor Noah Centineo said the app made him look forward to growing old.

"If I don’t look like this in 50 years I’m gonna be so pressed," he wrote.

Other stars who have taken to the trend include Carrie Underwood, Drake, Diplo, Jeremy Renner, Gordon Ramsay, the Jonas brothers and Lil Nas X, among others.
