"It was very romantic and on one knee," the Golden Globe winner told the newspaper. "I never thought I'd get married again."
Shepherd, 62, and her fiancé met through friends. She was previously married to David M. Ford from 1978 to 1982, with whom she has a daughter, Clementine. She was then married to Bruce Oppenheim from 1987 to 1990, with whom she had twins Cyrus and Molly.
Shepherd can currently be seen on Broadway in The Best Man and recently co-starred in Lifetime's The Client List, which will return for a second season.
