Kirstie Alley (whose “Veronica’s Closet” was just canceled by NBC), 49, and her live-in boyfriend, James Wilder (“Melrose Place”), 40, have officially split — some time ago, in fact. They “ended their four-year relationship two months ago,” her publicist told PEOPLE. Alley has two children, William True and Lillie Price, from her former marriage to actor Parker Stevenson.
