IT'S a hot celebrity wedding season. Pamela Anderson will tie the knot with Kid Rock this weekend in St. Tropez, sources say. They'll attend Sean Combs' White Party on his yacht either before or after they swap vows. Also in the marrying mood is Mick Jagger's ex, Luciana Morad. The model - whose very brief fling with the Rolling Stone resulted in a son, Lucas, and the end of Jagger's marriage to Jerry Hall - will wed Brazilian TV executive Marcelo Carvalho in Ilha Bela on Aug. 19. The invitations the couple sent out included a list of hotels in the area. "But they are so cheap," laughed our spy. "They are not paying for any of their guests, and they have the money." Meanwhile, Tom Cruise and Katie Holmes are not getting married this weekend, as reports suggested. According to Cruise rep Paul Bloch, "As far as I know the plans are for late summer, early fall." The ceremony will take place at one of Cruise's homes - not Holmes' hometown of Toledo, Ohio.
