Gregory Ralph Evigan (born October 14, 1953 in South Amboy, New Jersey), better known as Greg Evigan, is an actor who was a teen idol during the late 1970s and early 1980s. He auditioned for, and got roles in Jesus Christ Superstar and Grease, the musical (where he got the leading character). He married Pam Serpe on June 3, 1979 and they have three children.
Evigan is better known for his work in two television hits: 1979's B.J. and the Bear, where he starred as B.J., a truck driver whose best friend was a chimpanzee (named Bear), and 1987's My Two Dads. My Two Dads lasted until 1990.
It was with B.J. and the Bear (which actually began in 1978 as a made for television movie) that Evigan reached pop star status, and he began receiving cover from such magazines as Tiger Beat, Teen Beat and many other magazines geared towards teenaged girls.
Evigan has engaged in more than forty acting jobs since then.
