The Feb. 19 wedding of Baywatch babe Pamela Anderson and Motley Crue drummer Tommy Lee makes it official: There are six degrees of separation between the buxom blond and Michael Jackson. In her brief history of time in Hollywood, Anderson, 27, has emerged as the unifying center of the celebrity-dating universe. By careful analysis of the modeling, movie, and music worlds, she can be tenuously linked to Vendela ex-squeeze Jon Peters, who’s a onetime love of Barbra Streisand, who once adored the newly shorn Andre Agassi, whose romance with Brooke Shields puts him a hair’s breadth from Michael Bolton. Woven from glamour, tattoos, and wedding bells, this tangled web even ties the bombshell to the ubiquitous Mr. Simpson (O.J., not Homer). And if that doesn’t scare you, look at how pivotal Scott Baio is.
