Kim Kardashian Butt Selfie: See Sexy Photo Of Post-Baby Body In White Swimsuit; What Does Kanye West Think?

It's back and bigger than ever! Yes, we're talking about Kim Kardashian's booty. The reality TV star shared her most revealing, sexiest post-baby body selfie so far on Instagram late Wednesday, Oct. 16, at just four months after the birth of daughter North West, and she's looking great! Kim, who recently revealed that the Atkins Diet has been her secret to her weigh loss, uploaded a provocative picture with a lot of sideboob and a lot of butt, and people seem to like it, as it has over half a million likes.

"She is eating lots of lean proteins, healthy fats like nuts and avocado, carbs, fruits, veggies and cheese," a rep for Atkins told Us Weekly. "She wanted to be a healthy, nursing mom and not toxify her milk with her diet or lose weight too quickly. She's been doing Atkins since her doctor approved it at the end of June." She has been exercising too, according to an observer, who spotted Kim with her rapper beau, Kanye West at a Barry's Boot Camp in California. "They were cute," the eyewitness said. "[They were] smiling at each other in the mirror when they were running side by side on the treadmills."

And speaking of Kanye, the usually private performer wasn't private at all when he let the world know what he thought about his girlfriend's picture. He reposted the sexy pic on his Twitter page, writing: "HEADING HOME NOW." We can only imagine! According to TMZ, Kim's been on a serious sexuality kick lately, and on the most recent episode of her reality show, she talked about wanting to pose naked as soon as possible saying, "As soon as I get in shape, the first thing I want to do is Playboy or some nude shoot. I just wanna walk down the street fully naked."

What do you think? Would you want to see Kim Kardashian strip down? Or do you think we've already seen enough of her?
