CHARLOTTE, N.C. (AP) _ Television evangelist Jim Bakker's 17-year-old daughter, Tammy Sue, told PTL employees this week that she has married Doug Chapman, 24, a former PTL hotel worker and lifeguard, according to a published report.

Neither Chapman nor Tammy Sue Bakker could be reached for comment, The Charlotte (N.C.) Observer said today. Chapman's mother, Ann Hargett of Fort Mill, S.C., declined comment.

''This is private with them,'' she told the newspaper. ''They just want to be left alone.''

Chapman and his mother appeared at Tammy Sue's side Jan. 21 when Tammy Sue was host of PTL's ''Jim and Tammy'' show, normally hosted by Bakker and his wife Tammy Faye. Tammy Sue Bakker has been a regular singing guest and co-host on the show, and PTL promoted her first record album, released last year.

Bakker stepped down from the PTL ministry last month when news broke that he had had a tryst with a church secretary in 1980 and paid $265,000 in hush money. Mrs. Bakker has undergone treatment for prescription drug dependency.
