Britney Spears is an open book, and we love it!

The X Factor judge, and mom of two, was in a chatty mood with Lucky magazine about makeup, body issues and life with her kids.

Brit, who loves to play Candy Land with her boys, tells the mag:

    "I really just wear mascara all the time and powder, because I have zits. I get, like, these giant boxes of lip gloss and nail polish, and it's like candy."

As for what fiance Jason Trawick likes to see her wearing, she adds:

    "He says he doesn't mind that I sit around in sweats all the time. I never wear socks. I hate socks."

The Slave 4 U singer also talks about what her kids think of her job. Brit says:

    They try to figure out where I go when I go to film X Factor. They're like, 'Mommy's going off to be a superhero,' and then I get back, and they just see me as Mommy. And then when I'm back working on the show, they say, 'Oh, Mommy's a superhero again!'"

Love ya, Brit ... and your honesty!
