Two weeks after their separation, "Moonlighting" star Cybill Shepherd has filed for divorce from her husband of nearly two years, chiropractor Bruce Oppenheim.

A divorce petition citing irreconcilable differences was filed Wednesday in Los Angeles Superior Court, said Shepherd's publicist Cheryl Kagan.

Shepherd and Oppenheim were married on March 1, 1987. They are parents of twins, Ariel and Zachariah.
