Poll: What's the Official Summer Party Anthem?

Katy Perry! Britney Spears! LFMAO! Tell us whose sizzling single reigns supreme

BRITNEY SPEARS

The Femme Fatale has been killing it, peeling off hits like "Till the World Ends" and "Hold It Against Me" from her seventh album – her sixth to top Billboard's 200 Albums chart. Her latest offering: I Wanna Go, a classic Britney confection complete with a dance-along hook, unapologetic Auto-Tuning and, of course, a must-watch video, which includes references to Half Baked, her debut film, Crossroads (check out the marquee at the 2:30 mark), and the "Thriller" video.
