LOS ANGELES (AP) _ Deborah Shelton will return to ''Dallas'' in the role of Mandy Winger, mistress of J.R. Ewing, the actress' publicist said Tuesday.

An outpouring of fan mail was one of the reasons for bringing her back to the CBS series, said Randa Handler.

Last year Mandy headed for Hollywood to become an actress. She'll be coming back ''with a devilish twist to her character,'' Ms. Handler said.

Viewers will probably see her return at the end of March.

Miss Shelton will also soon be seen in a feature film, ''Hunk,'' a Crown Pictures release scheduled for release March 6.
