(PEOPLE.com) -- There may be an extra place setting around Jack Wagner's dinner table this holiday season -- and not just because he and longtime girlfriend Heather Locklear are no longer together. Wagner, 52, discovered earlier this month that he has a long-lost 23-year-old daughter from a "fling" he had with the girl's mother in the late 1980s, TMZ reports. The girl, named Carrie, introduced herself to Wagner backstage at a November 4 concert in Boca Raton, Florida. where the actor was performing with Rick Springfield. Less than two weeks after the encounter, Wagner and Locklear announced they had called off their engagement, saying planning their wedding was not allowing them enough time to spend with their children.
