Britney Spears has taken umbrage at being called a slut by Keira Knightley. In fact, Keira never called Britney out by name - but I think we all know who she was talking about when she made this remark about a week ago:
The whole celebrity thing is not magic. They are just real people proving they are sluttier than everybody else because they don’t wear any knickers.
Britney may be bombed out of her mind most of the time, but she still has enough command of her faculties to know when she's been dissed. And she is still able to manage a retort. Sort of. Said Britney in response to Keira:
Who's Keira Knightley? I guess she must need the publicity.
Let's set aside, for the moment, the hilariousness of Britney attacking anyone else for being a publicity whore, and focus on the "Who's KeiraKnightley?" remark. Now, it's possible that Britney was just trying to put Keira down by pretending not to know who she was - but, I think it's equally likely that Britney is just so out-of-touch that she honestly is not familiar with Keira. We may make fun of Keira on here, but there's no doubt that she's a big star - she was in three of the largest box-office hits of recent years and got nominated for an Oscar, plus her face is all over the tabloids and the internet. So, any human being who even pays a little attention to the goings-on in pop culture is going to know about her. But Britney? It's possible that Britney is so absorbed in being Britney that she honestly isn't aware of Keira's existence. In fact, I think it's even possible that if you mentioned the Pirates of the Caribbean movies to Britney, she would have no idea what you were talking about either. "There's movies about that ride now? That's wild, y'all."
Sorry Britney, but even Keira Knightley, a certified twit, could kick your ass in a pissing match. The only person you'd have any shot against is John Travolta's retarded son Jett - and that still might be a toss-up.
