Tammy Sue Chapman, 18, the daughter of fallen evangelists Jim and Tammy Faye Bakker, had some news for her father during the holiday weekend. "You're going to be a grandfather," she whispered to him at a reception honoring her parents. Shortly after her father's fall from grace last year, Tammy Sue married Doug Chapman, 24, a blond lifeguard she met while he was working at the PTL water park. There was no word on when the baby is expected, but in appearances this weekend with her parents Tammy Sue did not appear to be pregnant. Relatives say they don't know whether Chapman has found a new job since he no longer works at PTL, but in the past few months Tammy Sue has given several concerts at churches and auditoriums around the nation.
