It may not matter for much longer, but “Martin” co-star Tisha Campbell is returning to the show. Earlier this year, Campbell filed a suit charging star Martin Lawrence with sexual harassment and HBO Independent Prods. with not acting on her complaints. HBO Independent Prods., which produces the show for Fox Broadcast-ing, said all the parties involved have resolved their differences. Details regarding a possible settlement of the ac-tress’s suits were not disclosed.

Campbell, who has not been in the last several episodes, will return as Martin’s wife in new programs airing in May. Campbell’s departure has not been addressed in the show. “Martin,” which premiered in 1992, may be in its last season and Fox has not said whether it will return next season. Since a spinoff of the show starring Tichina Arnold is in the works, many expect the series will end after May.
