Kim Kardashian isn't the only member of the family whose in-the-buff bod is in demand.

A rep for Playgirl confirms they've offered Rob Kardashian $45,000 to strip down for the mag.

"While most people assumed we'd be interested in [Kourtney Kardashian's beau] Scott [Disick], my interest actually lies in the adorable Rob Kardashian," Playgirl rep Daniel Nardicio told E! News. "Rob is a perfect example of the classic Playgirl model, and we'd be proud to have him join the ranks of other quasi celebs to strip for Playgirl."

Though he adds the Keeping Up With the Kardashians' star, 23, would need to do a little prep work in the gym.

"I'd bring him to NYC to work with my trainer for a few weeks though," said Nardicio, "as he looks like he could use a few weeks prep before the shoot."

And though Rob has yet to respond to the offer, his big sis, 30, is likely in favor.

She recently told Glamour magazine of her 2007 Playboy shoot, "When Hugh Hefner himself asked me, I thought, I'm young, and this is iconic for me....And I think it looks great. I'll have those pictures forever."
