Kesha and Pitbull went 'Timber' at the 2013 American Music Awards (Nov. 24). The summer 2013 tourmates performed their lava-hot duet 'Timber' with a troupe of dancers and lots of stairs on the stage.

It wasn't until the final third of the song that Kesha and Pit met in the middle of the stage and did a little sexy bump and grind action. Those two have terrific vocal and onstage chemistry, so much so that we wouldn't be surprised if either of their significant others raised their eyebrows for a hot second.

Kesha rocked multi-colored strands in her usually blond hair and a pair of cowgirl boots, so pop's resident raunch-a-holic was relatively tame in her look. Meanwhile, the always dapper Pit wore his signature suit and aviator shades.

We've got to take a second to give it up to Mr. Worldwide, since he pulled double duty during the ceremony, serving as both the host and a performer. Pit earned his keep and Kesha helped him look good while doing it.

Yep, Kesha and Pit brought the AMAs house down and they yelled 'Timber' while they did it!
