Katy Perry

Who? Most sought-after female pop star in the US right now.
Why? Are you kidding? We want to see Perry kiss another California girl before she officially becomes married to toothy actor Russell Brand.
Listen out for … celebrated chick anthems “Hot N Cold," “I Kissed A Girl” and “California Girls."

Wonder Girls

Who? Korean girls who shot to stardom for their famous "Nobody" dance.
Why? You know the moves. You just need someplace to show them off without getting beaten up.
Listen out for … the infamous track “Nobody” and their latest self-indulgent track “Hot.”

Kanye West

Who? Bad boy rapper and producer who interrupted Taylor Swift’s award-winning moment to kiss Beyonce’s ass at last year’s Video Music Awards.
Why? We’re hoping he'll liven up proceedings by trash talking the government. That would stop the floods.
Listen out for … “Stronger," “Heartless” and his smooth-as-silk single, “Love Lockdown.”

Smashing Pumpkins

Who? Alternative rock band known for their guitar-heavy sound.
Why? They’re the kind of stars worth being groupies for and though they've broken up and reformed a number of times, Billy Corgan is still a singular talent.
Listen out for … hot favorites “Tonight, Tonight,” “Disarm” and “1979.”

30 Seconds to Mars

Who? L.A. rock band featuring the hot Leto brothers, and loads of guyliner.
Why? This is the closest you’ll ever get to sexy Hollywood actor Jared Leto. His great vocals are just a bonus.
Listen out for … “The Beautiful Lie,” “The Kill” and latest hit “From Yesterday.”
