13 Awkward Celebrity Photos Shared In The #PuberMe Challenge

#Puberme was started by The Late Show's Stephen Colbert and comedian Nick Kroll to raise money for Puerto Rico. Plenty of celebs joined in thus far to show the world they, like everyone else, had an awkward phase back in the day. For each celeb that participated, both Colbert and Kroll pledged to donate money, and in just a few weeks, they've raised over a million dollars. Here are some of our favorites.
