Cybill Shepherd was due back on the "Moonlighting" set this week after her Sunday wedding to chiropractor Bruce Oppenheim in a traditional Oriental ceremony at her Encino home. "There's no time for a honeymoon," Shepherd's publicist, Sheryl Kagan, said. Shepherd, 37, who is expecting twins in October, wore an orange, white and gold antique Japanese kimono over white silk pajamas during the short ceremony. Oppenheim, 38, wore a black silk kimono with black silk pajamas. About two dozen family members and friends attended the ceremony. Neither Bruce Willis nor Mark Harmon was reported among them.
