The brunette model and actress relived her role as lifeguard Lani McKenzie during an appearance on US breakfast show Today on Thursday (31 October).
Carmen, 41, looked seriously amazing in her skimpy red swimsuit and even gave male fans a treat by reenacting the famous Baywatch 'slow motion run' along a patch of sand.
She appeared in Baywatch between 1997 and 1998 and returned for the reunion movie Baywatch: Hawaiian Wedding.
Running around on live TV in the middle of New York City is a daunting task for anyone, but luckily Carmen had someone to share the moment with: Today show host Matt Lauer!
Matt showed his sense of humour by dressing in a swimsuit to become Pamela Anderson's Baywatch character CJ. "Is someone drowning?" he asks. "I brought my cans."
The Today show gang went all out for Halloween, channelling some iconic TV shows including The A Team and The Flintstones.
Carmen, meanwhile, is moving away from acting and into singing, preparing for the release of new song 'Work'.
