VIDEO : Kate Upton Channels Britney Spears In Upcoming Performance on Lip Sync Battle

Kate Upton isn?t messing around when it comes to her upcoming appearance on Lip Sync Battle. For a duel against '90s hitmaker, Ricky Martin, the Sports Illustrated Swimsuit cover girl channeled Britney Spears for her own sexy rendition of "...Baby One More Time?. Upton rocked a thigh-high schoolgirl miniskirt, tied-up collared shirt and pigtails secured with scrunchies. The 24-year-old steamed up the studio by slithering on the floor and grazing her legs while backup dancers danced along to the millennium songstress' signature hit. We'll just have to tune in on Thursday night to see what these two have in store.
