"I've always felt like I'm not pretty enough," the divorced mother of two tells Us Weekly. The insurance-agency owner says her ego was bruised when costar (and Gretchen Rossi's) called her Miss Piggy during a comedy performance last season. "It really hurt -- off-camera, I cried," Gunvalson admits.

Thus motivated, Gunvalson, who has had two breast augmentations, took action. Leavings kids Briana and Michael out of the loop, she had a plastic surgeon (one recommended by costar Alexis Bellino) inject her body fat into her face to erase wrinkles, thin her nose and insert a cheek implant.

"I'm still numb -- it'll take a year to fully heal," she tells Us. "But it didn't change me inside!"
