Buzz Bites (3/6/10): Lollapalooza Lineup Announced; Lady Gaga And Green Day To Headline

+ After a bit of a scavenger hunt, the band lineup has been announced for summer's Lollapalooza Festival. Green Day, Soundgarden and Lady Gaga will headline, while fans will also be treated to performances from the likes of The Strokes, Arcade Fire and Phoenix. (MTV News)

+ Justin Bieber has Twitter in a headlock, the charts in a choke hold, Funny Or Die in his back pocket, and now he can add "performing at the White House" to his resume. (PopEater)

Katy Perry and Russell Brand threw an Easter party this weekend. This is noteworthy because Katy Perry wore bunny ears, and that, by itself, is pretty great. (Just Jared)

+ Drake's album, Thank Me Later, isn't coming out until June, but that hasn't stopped Sean Kingston from covering the LP's first single, "Over." (Idolator)

+ Heidi Montag called in to the Ryan Seacrest show, and it was totally normal. Quick recap: She doesn't like to be hugged and wants to play Lara Croft in the new "Tomb Raider" movie because she has extensive training with knives and guns. That's not at all disturbing, right? (I'm Not Obsessed)
