Yesterday, our favorite Canadian crooner Justin Bieber performed as part of the White House's annual Easter Egg Roll. But while the Bieb is certainly a musical trailblazer (youngest artist to hit #1 on the Billboard chart in 45 years!), he’s not the only pop star to rub elbows with the Commander-in-Chief.

Flip through the gallery and decide for yourself.
