The former "Baywatch" actress -- who dated the "Blade" actor in early 2005 -- was seen kissing the star in the lobby of Miami's Fontainebleau hotel on Saturday night.

Later that evening, the pair went to nightclub Mokai where Pamela apparently locked lips with three other mystery men - one of whom is said to have been a drag queen called Elaine.

A source added to America's OK! magazine: "She walked back into the Fontainebleau at 11am the next morning with a young sexy guy, wearing her clothes from the night before."

The mother-of-two's wild night had begun with dinner at exclusive restaurant Blade, where she "flashed her boobs".

The star had also attended the red carpet at nightclub LIV where she launched the December issue of Ocean Drive magazine - of which she is the cover star - alongside photographer David LaChapelle and PETA head Dan Mathews.

On Sunday, the 41-year-old stunned onlookers when she arrived at the prestigious Art Basel Miami Beach fair wearing just a T-shirt and underwear.
