In the latest edition of What in the World is She Thinking? Pamela Anderson was spotted out and about in Miami this weekend, partying hard and locking lips with Stephen Dorff (remember him—of Blade "fame"?).

According to an eyewitness, Pam and Stephen were "making out" in the lobby of the Fontainebleau on Saturday night, before heading to a party to celebrate the Baywatch babe's Ocean Drive cover.

"She went to Blade for dinner, where she flashed her boobs," an insider tells OK!, before heading up to pose on the red carpet with David LaChapelle and PETA head Dan Mathews at LIV.

The partying continued until the wee hours, with Pam drinking Lucid Absinthe until 4am and running around South Beach with Stephen, including a stop at nightclub Mokai. Her night on the town didn't end until Sunday morning... with a new man on her arm!

"She walked back into the Fontainebleau at 11am the next morning with a young sexy guy, wearing her clothes from the night before," the source tells OK!.
