We've seen Kim Kardashian nude in Playboy.
Will her sister soon follow (birthday) suit?
"I like doing things for a reason, and not just because someone gave me a big check," Khloé told E! this week when asked about baring it all. "So I personally will say, not right now, but I can't say never."
It's hard to figure out why anyone would pose for Playboy for any reason other than to receive a big check, but let's move on.
Remember, Khloe did get naked in a PETA ad late last year. She says she lost 20 pounds for that campaign. How so?
"I've changed my eating," she said. "Eating is my hardest problem. I need sweets. That's my major problem. And I've been killing myself at the gym."
The slimmed-down star will have a chance to show off the new body in her upcoming, sisterly reality show, Kourtney and Khloé Take Miami.
"I actually was in a bikini on camera!" she said. "I've never done that and I wouldn't have ever thought to do that. And I have to admit, I was still insecure... I've just got to tone up more, but I never would have done that before - ever. I would rather have died."
You can see Khloe alongside a bikini-clad Kourtney below. Take a close look and then answer the poll question that follows...
Which sister would you prefer to sleep with?
