Descended from European royalty, Catherine Oxenberg caused a sensation when she played Lady Di in "The Royal Romance of Charles and Diana" (CBS, 1982). Her international glamour served her well as Amanda Carrington, the daughter of America's favorite villainess Alexis (Joan Collins) on "Dynasty" (ABC, 1981-89), and she hosted an episode of "Saturday Night Live" (NBC, 1975- ) at the peak of her fame. Oxenberg left "Dynasty" after two seasons and struggled to find a suitable follow-up, appearing in Ken Russell's cult horror flick "The Lair of the White Worm" (1988), the downbeat "Charles and Diana: Unhappily Ever After" (ABC, 1992), and one season of the lightweight action series "Acapulco H.E.A.T." (syndicated, 1993-99). Her nine-day, annulled 1998 marriage to legendary producer Robert Evans made headlines, but she had better luck marrying actor Casper Van Dien in 1999. The couple starred in the Christian thriller "The Omega Code" (1999) and a reality show based on their lives, "I Married a Princess" (Lifetime, 2005). Although her stardom was brief, Catherine Oxenberg could boast a life as colorful and interesting as that of many of her royal relatives.
