Kourtney Kardashian was always seen as the "good girl" of the Kardashians, but not anymore. Kourtney just posed for some nude and explicit pics - for GQ Magazine in Mexico.

Kourtney has been doing the most recently - to try and increase her fame. And she's single too - right now she's the only Karadsahian that hasn't been wife'd up.

So this latest GQ explicit spread shouldn't be all that surprising to onlookers.

Kourtney split with her baby's father Scott Disick two years ago. She started dating model Younes Bendjima almost immediately. But Younes and Kourtney split up three months ago.

"I am very comfortable in my own skin," she says. "I like to be naked in my house and I think it is important to show positive images of our body."

Of course, she's willing to work hard for the results, too. Kourtney says that after her role as a mother, exercise is what's most important for her.

She also spoke about other things that are important to her in the interview:

"I learned something from all of the diets I tried in the past and incorporated them into my lifestyle, but I'm not so strict anymore. Fifth, I would put the decoration because it is where I express myself creatively. Then beauty, not so much from the point of view of makeup, but rather define it as 'self-care' -- do things to feel better, like a massage, for example. And in the end, it would be fashion -- which is my passion -- but I don't give it so much time or attention anymore."
