Justin Timberlake Warms Up for Grammys With Timbaland (VIDEO)

Justin Timberlake got down last night, as can be seen in the video below. We highly recommend you watch this fan-shot clip because it will make you want to get down too.

Mr. "Suit & Tie" was the surprise guest during his producer-of-choice Timbaland's gig Friday night at The Congo Room in Los Angeles. Timberlake, who will perform at the Grammys this Sunday, warmed up with Timbo at the pre-Grammy event by hopping onstage for their infectious collaborative track “Carry Out.” Now we can't get the song out of our head.
