Amazing Celebrity Glow Ups, Ranked

40. Kirstie Alley

When someone glows up, they undergo a major and impressive transformation. Of course, when someone becomes a celebrity, they can suddenly afford much better hair or a fresh set of sparkly whites. Some of these amazing celebrity glow ups happened because of star power, others because of the natural passing of time, and others because of an upcoming role. Whatever the reason — these celebrities have transformed! Let’s take a look at the celebs that went through a major glow up…

40. Kirstie Alley

Kirstie Alley is best known for her role as Rebecca on Cheers, as well as for her performances in Summer School, Madhouse, and Drop Dead Gorgeous. The actress appeared on The Dr. Oz Show in 2012 and admitted to struggling with her body image since 2003. She then teamed up with Jenny Craig between 2004 and 2007, but continued to fluctuate in the years after.

After Gigi became the world’s most sought after model, Bella followed in her footsteps. With the help of some high fashion and contouring — plus a little nip and tuck — the younger Hadid sister really came into her own. Bella Hadid, though you had a good head start, you certainly glowed up.
