The Seavers on Growing Pains were the perfect family-next-door, and every girl in the late '80s wished that Kirk Cameron (pictured in 1988) could be her neighbor. Cameron was just 14 when he began playing wisecracking teen Mike Seaver on the show, which ran from 1985 to 1992. Before long, he was appearing on the cover of every teen magazine and receiving 10,000 letters a month from lovesick fans. But when he converted to Christianity halfway through the series, he resolved to stop letting the attention get to his head. At the age of 20, Cameron decided to settle down, marrying actress Chelsea Noble (who played Mike Seaver's girlfriend Kate on the show).
