Rihanna, Katy Perry Rake In VMA Noms

If you've been congratulating yourself on having finally gotten the insanely catchy chorus of "Call Me Maybe" out of your head...well, good for you! And enjoy it while it lasts, 'cause it won't be long before we stuff it right back in there. The song is just one of the year-defining earworms to get a nomination nod from the 2012 MTV Video Music Awards, along with a lot of familiar tunes and favorite faces.

Among the nominees are Hollywood Crush regulars Rihanna and Katy Perry, facing off for Video of the Year, as well as Best Female Video (and that's just the tip of the iceberg for Ri-Ri, who leads the pack with five nominations total). Also on the radar: Justin Bieber and his latest hit, "Boyfriend," for Best Male Video; One Direction and Frank Ocean for Best New Artist; and, of course, Gotye and the impossible-to-stop-singing "Somebody That I Used to Know" (sing it with us now: USED TO KNOOOOOOO-OW!)

The VMAs air Thursday, September 6 on MTV, and voting is open now for all categories. Want to see the full list of nominees? Click to see our complete roundup!
