Kendra WilkinsonIt wasn't long ago that if Kendra Wilkinson worked for SoBe drinks, she would have been part of the company's nude body painting celebration like 'Twilight' star Ashley Greene.

After all, Wilkinson was an unknown model wearing nothing but strategically-applied paint at a party when she met Hugh Hefner and the rest is Playboy history.

But the new mother tells PopEater that she's moved onto other projects with SoBe -- like the Zero Inhibitions Bracket Challenge -- and retired from service as a human canvas.

"I don't know if I can do the whole body painting thing," she says in PopEater's video. "That was when I was 18. Right now, I'm a mom."

Sniff.
