"The Vampire Diaries" alum Nina Dobrev is taking on football quarterback Tim Tebow in this week's "Lip Sync Battle" face-off, and it's promising to be quite a hot, sweaty match. So far, Spike TV has teased fans with two preview videos, one showing Tim channel his inner Rocky Balboa for Survivor's "Eye of the Tiger," and another showing Nina channel her inner Marvin Gaye for "Let's Get It On."

Marvin was never this sexy, though, and Nina even works her charms up and down Tim's body, perhaps hoping she can distract him before his second battle. Tim really brings his A-game to his Rocky performance, and that video shows a glimpse of Nina in football gear, which gives us a hint to her second battle.

Here are the two previews:
