Justin Bieber to Appear on American Idol

Justin Bieber hollers across the street to a fan as he makes his way back to his hotel in Beverly Hills on Sunday afternoon (March 28).

The 16-year-old singer just performed at the 2010 Kids Choice Awards on Saturday night.

Justin will be staying in town at least until Wednesday, where he will be performing on American Idol.

JJJ fan and reader Amna also sent in pics of Justin at Disneyland with Ryan Seacrest. Thanks, Amna!
