Our favorite part of every Thursday is when stars dig through their photo albums and old desktop folders to find the cutest baby pictures of themselves... and then post them on the Internet.
In honor of Throwback Thursday, M rounded up some of the best TBT photos of some of your fave stars. All you have to do is click through the gallery below and either highlight or double-click the black box to play the TBT guessing game!
Check out the throwback gallery below and give each pic your best guess! How many did you get right? Tell us in the comments!
