Invitees to Pamela Anderson’s and Tommy Lee’s wedding ceremony (it’s their third) on New Year’s Eve in Malibu needn’t worry about the dress code. Tommy’s telling British papers that the entire ceremony — including bride, groom and guests — will be performed in the buff. “Being naked will make us all aware of how much a part of nature we really are,” he says. The ex-“Baywatch” babe and the former Motley Cru drummer reunited in February after they were divorced last year (when Lee was sentenced to three months in jail for assaulting Anderson). Their very first wedding, in 1995, was comparatively formal: She wore a bikini, and he wore shorts.
