Justin Bieber just arrived at the White House where he's going to perform for President Barack Obama ... and, more importantly, the Easter Bunny.
Biebs -- along with the cast of "Glee," Reese Witherspoon, J .K. Rowling and more -- is at 1600 Pennsylvania Avenue for the annual Easter Egg Roll.
The 16-year-old also performed at the White House for Christmas.
