Kate Upton Breastacular As Britney Spears On Lip Sync Battle (VIDEO)

Kate Upton is fresh off the heels of her unreal Sports Illustrated: Swimsuit Edition cover, and already she's making headlines again for all the right reasons. The walking definition of curvy takes to the stage of Lip Sync Battle to recreate Britney Spears' infamous Baby One More Time video. Yes, it's cliche. Also, yes, it's still awesome.

The Internet is losing it over the performance, and it might just have something to do with Upton's major cleavage that seems to want to jiggle right out of her bra. Upton's full performance for Lip Sync Battle will debut on April 20th, but this preview more than helps us get our fix. The folks at Spike TV are smart enough to know that a writhing, barely covered Kate Upton dressed as a fellow sexy symbol will equal viewers. This commercial will be covered in Marketing 101 until the end of time. 

Britney Spears left a legacy of too-hot-to-handle looks throughout her career, but nothing is quite as iconic as her sexy Catholic schoolgirl ensemble from her breakout hit way back in the last Millennium. Upton's spin on this classic mostly involves those mams that just need to be squeezed, and she's even joined by a bevy of bangable backup dancers to boot. Okay Spike TV, you got us.
