Britney Spears fans, rejoice! (That’s me! I’m rejoicing! Love Britney!) The singer’s first new single in awhile (okay, excluding that meh song she did for the Smurfs movie) leaked online well in advance of its expected Monday night release. “Work Bitch” is pretty basic lyrically — surprising, I know — and seems to be mostly about Britney’s newly returned work ethic. Or something. Whatever. It’s a total club banger and I am now even more excited for Brit’s next album of songs I can pretend to strip to in the privacy of my bedroom.
