What in the…? Pamela Anderson's always changing face never ceases to surprise us, and the model — who's opened up about her plastic surgery in the past — once again stepped out looking unrecognizable at an event in London.

The 49-year-old, who's currently dating WikiLeaks founder Julian Assange, attended the launch of the Coco De Mer Icons Collection at Albert's Club on April 3. And while her colorful floral dress certainly stood out in a sea of black, it was her face that caught everyone's attention.

In recent months, the former Playboy Playmate has been toning down her look with less makeup and hair extensions, but fans think the mother-of-two may have gone under the knife again.

While the entire world knows about Pamela's boob job, the blonde bombshell has kept the details of her other procedures relatively close to her chest (no pun intended). "I'm not against plastic surgery, what I've had done will stay with me and that's fine, but I don't want anything else. I'll do facials but I don't want to go down the scary route and have knives plunged into me," she previously explained.

In fact, the Baywatch star recently admitted to enjoying the aging process. "I have great older female role models in my life, including my amazing mom, who have glitz, glamour and all sorts of fun. Getting older isn’t the end. I know I have so much to look forward to," she told W magazine.

"I look back at pictures of myself when I was in this awful relationship, and I looked 20 years older,” she added. “I know it sounds like a cliché, but happiness has a lot to do with beauty. Calm, peacefulness, and not-constant stress are very, very important to feeling beautiful and confident."
