Pamela Anderson was definitely in the mood to party at the grand opening of Sapphire Gentlemen’s Club.

Looking very much at home in her skimpy shirt and teeny shorts, the former Baywatch star spent the evening chugging champagne with boyfriend Jamie Padgett and a group of scantily-clad 'lovelies' in the New York venue's VIP booth.

Pam's hosting gig stretched to not speaking to reporters and shouting "Sapphire rules!" into a microphone from the curtained VIP area, reports the New York Observer.

It's also claimed that the star studiously avoided Shannen Doherty, who was also in attendance.

Both aging beauties used to be married to Paris Hilton's sex tape co-star Rick Salomon.
