It's Britney Spears' job to be sexy, toss her weave around, rub her body, and shake some T&A.

Britney does just that in her new video '3' from her upcoming disc, The Singles Collection. I like the moves Britney does in bed in her "My Prerogative" video more than the choreography here, and Sasha Fierce beats Brit in the sexy game any day, but Britney's here to entertain, not wow us.
