Britney Spears: 'I Can't Be Like Kim Kardashian, I'm A Tomboy' (PICS)

Britney Spears is currently gearing up for her debut appearance as a judge on The X Factor USA, meaning we'll be seeing a lot more of her looking glammed up on our TV screens.

However, the singer has admitted she won't be keeping her new polished look off-camera.

In an interview with US Elle magazine, Brit said she is not a "believer" in wearing make up all the time and can't be like other American stars such as Kim Kardashian.

She said: "I love my jeans and my sweats- I’m really just a tomboy at heart. 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?

"On the other hand, when you do wear those sweats, you’re like, Oh God, I should step it up a notch."

The star also said that she has finally learned to deal with the constant media scrutiny after many years in the spotlight.

"I guess I’ve been under the microscope so long that I don’t even pay attention to the nonsense anymore," she said. "I gave up getting upset about things people make up about me a long time ago."

Britney is currently engaged to Jason Trawick, who she posed with during the photoshoot for the magazine.

He popped the question to Britney in a romantic proposal last year and in the interview he told of how she was the one who first chased him in the beginning of their relationship.

He said: "It was kind of one of those things where she moved, like, turned around, so we were face-to-face, and then-" before being interrupted by Britney.

"Okay, that’s enough information, sweetie. It was sweet, just say that."

Aww, bless!

The full interview appears in this month's issue of US Elle magazine, out 18 September.
