Janet Jackson, Snooki and More Celebs Share Their 'Glow Up Challenge' Transformations

Janet Jackson, Nicole "Snooki" Polizzi, Lori Laughlin and more stars are sharing their "glow up" transformations.

It all began when a photo challenge went viral on the Internet recently. People began to share posts on social media that showed how they have changed over the years. The actual name of the challenge has varied, as some have called it the "10 Year Challenge," while others have titled it as a "Glow Up" or "How Hard Did Puberty Hit You Challenge."

Nevertheless, all variations of the trend have included a post that shows two photos side-by-side: one being a throwback pic and the other a more recent snapshot. And like many fun social media challenges, celebs have joined in and the results are incredible.

Snooki, for example, shared an old pic of her crawling on the sand back in the early "Jersey Shore" days and compared it to a selfie of her now smiling with her two children in an innocent selfie. Snooki's co-stars Mike "The Situation" and JWoww also took the challenge on Instagram.

A few "Real Housewives" have also joined in. "RHOA" star Kandi Burruss posted not one, but two side-by-side photos to show her wild transformations. She captioned the post: "Since everyone is doing the #thenandnow here we go here is 2009 vs 2018 for first two group pics and for last group 2000 vs 2018!"

Many of the stars appear to be frozen in time or even aging in reverse.
