Model-actress Kate Upton is facing off against Ricky Martin on the upcoming episode of Spike TV's Lip Sync Battle, and she's pulling out all the stops to make sure she doesn't lose.

In a video teaser that was released earlier this week, Upton slips into a sexy schoolgirl costume for her lip-dub of Britney Spears' "...Baby One More Time," during which she crawls on all fours, gyrates her hips, and joins a troupe of girls for a choreographed dance.

On Wednesday, Spike teased Martin's pantless performance of Bob Seger's "Old Time Rock & Roll." Upton and Martin's full episode airs Thursday at 10 p.m. ET on Spike.
