We love photos of celebrities before they were famous... it's like seeing a dog walk on its hind legs or seeing a teacher outside of school.

TBT photos remind us there was a time before anyone knew who these celebrities were. Before they were gracing magazine covers or attending film premieres, they were just like us, smiling awkwardly into a camera for school photos, putting on talent shows with their siblings, or cheesing hard on Christmas morning. 

And, thanks to Instagram and Twitter, we are more connected than ever before to our favorite celebs. Stars can't seem to resist a good "TBT" of "FBF," meaning there's no shortage of golden throwback photos. Here are some of the best of the best.
