Keira Knightley's $50,000 allowance

Keira Knightley wants to balance being famous with being a regular Jane.

So to keep herself in check and in the land of the "normal," the actress gives herself a $50,000 annual allowance.

"I think living an [expensive] lifestyle means you can’t hang out with people who don’t live that lifestyle," Knightley tells Glamour magazine in its July issue. "It alienates you. Some of my best, most hilarious times have been in the least luxurious places."

Of course, just because she tries to stick to $50,000 a year doesn't mean she does. "I mean, if I want or need something that goes over that, I get it," Knightley admitted, "but, yes, around that."
