Black Keys: Best Kiss Experts At The Movie Awards?

'I'm so worried about how we're going to vote for Best Kiss,' Patrick Carney jokes to MTV News before tonight's performance.

UNIVERSAL CITY, California — The Black Keys will put “Gold on the Ceiling” when they take the stage at the 2012 MTV Movie Awards tonight. So what should fans of the Ohio rockers expect when they storm the show?

“Well, without spoiling it,” Dan Auerbach teased MTV News during rehearsals at the Gibson Amphitheatre in L.A. But, unfortunately for fans, MTV News had to censor his answer so we wouldn’t ruin the big surprise.

In addition to performing, the guys will also get to chill out with some of the biggest stars on the planet, a concept Patrick Carney said really puts him at ease. “We feel really comfortable in these environments,” he joked. “You might not know this, but we were child stars.”

While the performance should make some headlines, so will whichever lucky couple nabs the highly coveted Best Kiss prize. When asked if they would be voting for Kristen Stewart and Robert Pattinson’s smooch in “Breaking Dawn – Part 1,” the guys didn’t yet know which make-out session deserved their vote.

“I’m so worried about how we’re going to vote for Best Kiss,” Carney teased.

To see what the guys weren’t allowed to tell you, you’ll have to tune in to the big show tonight, which will also feature performances from Fun. , Martin Solveig and Wiz Khalifa . It all goes down at the Gibson Amphitheatre in Universal City, California, at 9 p.m. ET/PT.
