Amanda Peterson, who starred opposite Patrick Dempsey in the 1980s rom-com Can't Buy Me Love, has died at age 43, TMZ reports, citing her father.
According to the site, Peterson was discovered at home in Greeley, Colo., on Sunday, July 5, after her family grew concerned that they hadn't heard from her in a couple of days. An official cause of death has not yet been determined.
"She had some illness and a sleep apnea problem that may have contributed," her father told TMZ on Monday, July 6.
Peterson got her start in Hollywood in the early 1980s, when she scored a small part in the movie musical Annie, as well as bit roles in shows including Silver Spoons and Boone. Her big break, though, was in 1987's Can't Buy Me Love.
Peterson played popular high school cheerleader Cindy Mancini, who agrees to fake-date Patrick Dempsey's nerd character in exchange for money. The movie inspired a remake in 2003, Love Don't Cost a Thing, starring Nick Cannon and Christina Milian.
After Can't Buy Me Love, Peterson continued to act for several years before leaving showbiz for good in the 1990s. Her last credit on IMDb is 1994's Windrunner.
