“I don’t watch a lot of TV, but I love ‘Will & Grace,'” Glenn Close, who will guest star on the sitcom this Thursday, May 2, tells PEOPLE. The actress, 55, turns up on the NBC hit show as a wacky, drug-abusing bisexual photographer who locks lips with the two leading characters. “Now I’ve kissed Will and Grace,” muses Close. “I bet people are going to think I’m gay now! To some I am already a gay icon because of characters like Cruella De Vil (in Disney’s “101 Dalmatians”) and Norma Desmond (in Broadway’s “Sunset Boulevard”).” Close is more concerned about what her daughter Annie, 14, will think. “There were some really racy scenes and my character is very messed up. My daughter will probably be mortified.” As for landing the guest spot to begin with, “I approached them. I hadn’t worked for a while at that point,” said Close, will soon start shooting a drama called “Safety of Objects” as well as costar with Patrick Stewart in a Showtime TV adaptation of “The Lion in Winter” (the 1968 movie version starred Peter O’Toole and Katharine Hepburn, who won an Oscar for her portrayal of Eleanor of Aquitaine). And as for the smooch — or, really, smooches: “Will and Grace were both great. It wasn’t like a deep, French kiss, but it was fun.”
