Celebrities are posting embarrassing photos of themselves to help raise money for hurricane victims in Puerto Rico.

It's after the hashtag #puberme was created on Twitter.

Stephen Colbert, who hosts the Late show in America, and actor Nick Kroll kicked off the fundraising challenge.

For every celeb who posts a photo, the Late Show host will donate money to Puerto Rico hurricane relief through his charity, the Americone Dream Fund.

Hurricane Maria was the most powerful hurricane to hit Puerto Rico in nearly 90 years.

Launching the challenge, Stephen Colbert set the bar pretty high.

And soon, other stars were joining in.
