Go Brittany Go!!!

We are BEYOND ecstatic about Glee's senior prom episode next week!!

And this jewel of a sneak peek takes us smack dab in the middle of their Prom-asaurus!!

Ch-ch-check out Brittany's bangin' performance of Ke$ha's Dinosaur with these EXTREME dance moves (above)!!!

Nice to see her still carrying that Britney Spears confidence, riight? ;)
