Pamela Anderson, who is still among the contestants on Dancing with the Stars, made a cameo appearance in the promo for David Guetta and Fergie's new single Gettin' Over You recently.
As soon as she arrived on the set of the video shoot, she stripped down to her skimpy lingerie.
The little clothes she kept on during the video shoot were all gone after the video wrapped and she hit the after party at David LaChapelle's studios.
After a few hours of drinking and partying, Pamela decided to treat partygoers to a special performance, removing all her clothes to dance naked for their amusement.
"By the end of the night, Pam was dancing around in nothing but her birthday suit," the source told E! Online.
"Everyone was shocked, but everyone was having fun."
