Britney Spears has dyed her hair blue, and it looks more like one of the kids spilled some Kool-Aid on it.

Seriously … it looks like an accident.

Britney recently revealed that she’s not all glitz and glamor, like a certain socialite.

“I love my jeans and my sweats – I’m really just a tomboy at heart,” she says.

“So it’s really hard for me to be like Kim Kardashian and be makeup-and hair-ready every time I go out of my house. I’m not a believer in that, you know?”

Britney isn’t only a hot mess, according to Simon Cowell, she’s also pretty mean.

“She’s surprisingly quite mean,” Simon Cowell said in a press conference yesterday. “She can’t say no quick enough. She’s quite difficult to please.”

Cowell added that he’s been pleased so far with Spears’ performance on the reality-singing competition, which kicks off its second season next Wednesday on FOX.

Her hair is blue!
