Hayden Panettiere, Wonder Woman, Selena Gomez and More of This Week’s Biggest Transformations

So many changes, so little time.

This past week, multiple stars stepped out with new hairstyles, including Hayden Panettiere making her return to social media by debuting a dramatic haircut and Selena Gomez sporting a new cut and color while promoting her new album. Plus, Kaia Gerber is rocking a chic new look that even her model pals are gushing over. Hm…anyone else feeling inspired to hit their hair salon before Christmas? 

But some major blockbusters also underwent some transformations, with Wonder Woman debuting an epic new look in the first trailer for the highly anticipated sequel and Ghostbusters introducing us to a whole new cast of characters with ties to the iconic ’80s film. New era, new look, new ghosts! 

And in a new interview, Rebel Wilson revealed her unexpected weight loss while filming Cats, in which she co-stars with another major star undergoing a transformation this week: Taylor Swift.
