This sizzling number topped the Billboard Hot 100. But that's not the only news it made. The electropop track was accompanied with a superhot video that had everyone going gaga over Britney's avatars.
The video directed by Joseph Kahn (Love The Way You Lie fame, featured Britney as a secretary, a waitress, chauffeur and the seductress in the sauna. And the disguise was key to unraveling the womanising boyfriend.
This video was also a 'take that' from Britney to her critics. The sauna scene especially silenced all talk of her weight issues. It was included specifically by Kahn. "I knew that the whole world would be watching, so I wanted something in there that stated, 'This is Britney, this is why you should respect her'," said the director.
We're not complaining!
