Laverne patched it up with Shirley, but Bruce Willis says not to expect a reunion of Moonlighting's David and Maddie (Cybill Shepherd) anytime soon. ''Let me just say I don't think so,'' says the Die Hard With a Vengeance star, who was rumored often to bicker with Shepherd throughout the series' four-year run. True to form, Shepherd has a different opinion. ''I'd love to do Moonlighting: The Movie with him,'' she says. Each agrees, however, that the other has done well. ''I saw Cybill a couple of times,'' says Willis. ''I like it she's cool in it.'' Shepherd, meanwhile, hasn't caught the latest Die Hard, but says Willis was ''wonderful in Pulp Fiction.'' Successes aside, Willis has put his TV days into perspective. ''Sometimes I figure if the first Die Hard movie had failed, I'd still be saying, 'Cybill, would you come on?'''
