In case you feel like celebrities never have an "awkward" phase, take a good look at the headshots they shared on social media on April 27. Thanks to the power of viral hashtags, stars such as Natalie Portman [1], Karlie Kloss, Emma Watson [2], and more posted their throwback pics to celebrate Old Headshot Day, and the snaps are true treasures. It's incredible to see how much some of our favorite stars have changed — or haven't changed (I'm looking at you, Stephen Colbert [3]). Catch a glimpse of Melissa McCarthy in a tiny cowboy hat and Chloë Grace Moretz looking precious beyond belief in the photos below.
