Michael Jackson presents Princess Diana and Prince Charles with some souvenirs as his "Bad" tour gets under way at Wembley Stadium in London. The royal couple received cassettes, tour jackets and donations to the Prince's Trust and other charities.Michael J. Fox, star of NBC's "Family Ties," is planning to marry actress Tracy Pollan, his former girlfriend on the show, the actor's agent said. Fox's agent, Peter Benedek, said through an assistant only that the actor was getting married but wouldn't say where or when. However, a source close to the actor said Fox would "be married by Sunday night." Another source said the wedding would take place in a country inn, probably in Vermont, where Fox owns a 100-acre homestead. Both sources demanded anonymity. Pollan, 27, played the girlfriend of Fox's character, Alex Keaton, on the popular sitcom before going on to film roles. Fox, 26, started dating Pollan last spring after her break-up with actor Kevin Bacon, People magazine reported in May. The couple also co-starred in the film "Bight Lights, Big City."
