24 actor Kiefer Sutherland has reportedly split from his girlfriend Siobhan Bonnouvrier.

The star and the Allure magazine editor are said to have ended their relationship after three years together.

A source told US Weekly that the split was amicable and that they are deciding how to proceed. They said: "They've split for now [but are] transitional and ever-growing."

Sutherland has been linked with another woman, New York socialite Eleanor Propp, although she denied any involvement with the actor, telling the New York Post: "I am not dating Kiefer. We are just friends."

Sutherland and Bonnouvrier began dating in early 2008 and were reported to be engaged last year when Bonnouvrier was photographed wearing a ring on her left ring finger.

The actor was previously been married twice, to Camelia Kath, from 1987 to 1990 and Elizabeth Winn from 1996 until 1999.
