He may not take home a Grammy award tonight, but Adam Levine still wins the award for the hottest arm candy!

The Maroon 5 frontman held on tight to his model girlfriend Anne V, who donned a sexy black dress that was slit so high, and cut so low, she almost made an Armani-clad Rihanna look conservative!

The happy couple walked the red carpet with Maroon 5 band members James Valentine, Mickey Madden, PJ Morton, and Matt Flynn, and the group is nominated for Best Pop Duo/Group Performance for their hit song “Moves Like Jagger,” along with Christina Aguilera.

Adam Tweeted after hearing the news of Whitney Houston's untimely death, “Tomorrow night at the Grammys, the only person on our minds will be Whitney Houston.”
