Britain born, Sheridan moved to the U.S. to be a model in the early 1980s but soon began acting. She had a handful of small TV and film roles under her belt when she rocketed to stardom as a manipulative beauty on the prime-time soap Knots Landing in 1986. Real-life romances with Scott Baio, Michael Bolton and a brief marriage to Harry Hamlin served to keep her in the tabloids. After the series ended in 1993, Sheridan continued to work, mostly in TV-movies. But she returned to the spotlight as a serial divorcée on Desperate Housewives in 2004. When not working, Sheridan is an avid equestrian.
