Janice Dickinson, an outspoken fan of plastic surgery, has some new work she will soon take public.

Usmagazine.com has learned exclusively that Dickinson, 52, the self-proclaimed "world's first supermodel," underwent a tummy tuck and "mini neck lift" Monday in Beverly Hills. The surgeon: Dr. Frank Ryan, the plastic surgeon to the stars who famously augmented the breasts of Hills star Heidi Montag.

A source tells Us that while "Janice knows people will think she didn't need a tummy tuck," she's been complaining about "a lot of extra skin" on her lower abdomen and wanted tighter abs. The source adds that she opted for the mini neck lift as an after thought because "she might as well since she was going under."

According to the source, Dickinson, star of Oxygen Network's Janice Dickinson Modeling Agency, is now resting at the Serenity after-care center in Santa Monica.

Just prior to having a facelift in 2004, Dickinson explained the appeal of plastic surgery to Entertainment Tonight: "I consider plastic surgery important because I'm in front of the camera, I still model, and, quite frankly, I was noticing my skin looking like a turkey wobbler. I'm just trying to hang on to what I got."

A rep for Dickinson couldn't be reached for comment.
