Pam Anderson slipped back into her Baywatch swimsuit Wednesday night.

The actress and model, now 42, wore the famous red one-piece down the catwalk at the A*MUSE by Richie Rich show during the Funkshion Fashion Week in Miami Beach.

Considering that the suit still fits, would she ever play C. J. Parker on the big screen?

"Never! I'm not going do it," she told "I liked the TV show. I don't like it when they ruin it by making a movie out of it."

Though Anderson looks better than ever, her former Baywatch costar Nicole Eggert -- who will complete in the next season of VH1's Celebrity Fit Club -- has packed on the pounds. Anderson told Us, "I haven't seen her in a long time."

So how does Anderson - mother to sons, Brandon, 12 and Dylan, 11 - stay in such great shape?

"It's all natural," PETA Vice President (and pal) Dan Mathews told Us. "I mean, even if she's had to fly all night to meet with some government official with little sleep, she still has this upbeat attitude, and it's very much about determination with her. She's a great mother. Her kids are [older], ready to give her headaches, but she's great with them."
