Actor Tom Poston, 79, and fellow "Bob Newhart Show" alum Suzanne Pleshette, 64, will marry on May 16 in New York, where they first met 30 years ago, reports Variety columnist Army Archerd. They will then hold a reception in L.A., where they live, on May 26. When Poston proposed marriage earlier this year, Pleshette told PEOPLE, "It's sounds like a good idea to us." This will be her third marriage. Her husband since 1968, Tommy Gallagher, died on Jan. 14, 2000. In 1964 she was briefly wed to heartthrob Troy Donahue. Poston has previously been married three times.
