Grammy Arm Candy: 25 Couples Who Stunned Us On Music's Biggest Night

Valentine's Day came early this year, as some of the hottest couples in the music biz took a stroll down the red carpet at the 2013 Grammy Awards. Musicians aren't known for ever being short on arm candy, but this year's ceremony seemed even more paired off than normal. Seriously, if you were invited the Grammys and you didn't take your boo, you're gonna be in the doghouse til next year!

The Grammy for "Most Controversial Couple" definitely goes to Rihanna and Chris Brown, who snuggled up together in the audience just as they promised/threatened they would. Kat Von D also turned up with DJ deadmau5. But not all of the duos sketched us out. Amber Rose and her baby bump lit up the red carpet with her fiance Wiz Khalifa by her side. Jack Osbourne turned up with his new wife Lisa Stelly. More married mates included Alicia Keys and Swizz Beatz, plus Nicole Kidman and Keith Urban.

For a while there we couldn't figure out how Girls star Allison Williams was getting chummy with Katy Perry for photographers. That definitely would have been an interesting development on the Hollywood dating scene, but it turns out that Katy's beau John Mayer is besties with Allison's BF, College Humor CEO Ricky Van Veen. There's a seriously interesting double date waiting to happen!

Neil Patrick Harris made an appearance with partner David Burtka because, hey, what's an awards show without NPH? But by far and away, the cutest (non-romantic) couple of the night had to be little Sophia Grace and Rosie, the pint-sized pre-divas who brought us the sweetest version of "Super Bass" of all time. See more of your favorite two-somes in the gallery above!
