The song was written by Max Martin and Dr. Luke—what isn't these days?—with Avril Lavigne, and apparently was recorded by Avril for her last album The Best Damn Thing. I wouldn't know, because I don't listen to such trash.
If you tell me something like, "This was a Boy Krazy B-side, from their third European single," I'd be all like, "Hold on, let me cue that shit up—I got it right here!"
Anyway, in the video, it looks like Leona is giving her boyfriend, played by Gossip Girl "heartthrob" Chace Crawford, some kind of sex in a car. Then she hands him a pile of cash, so he must be a hooker. Then the cops arrest her.
Leona needs to learn how we roll over here in America. Public sex with whores is best done in shopping cars in an alleyway and McDonald's Playlands. Not in a car in a parking garage.
Have British people learned nothing from George Michael?
