Kiefer Sutherland splits from girlfriend

New York: `24` star Kiefer Sutherland is single again after ending his three-year-old romance with Siobhan Bonnouvrier.

The twice-divorced actor has been dating Allure magazine style director Bonnouvrier since 2008.

Last year, the 44-year-old star sparked rumours he had proposed to Siobhan after she was spotted wearing what appeared to be a large diamond engagement ring during a romantic holiday in Italy.

Sutherland, who was once engaged to Julia Roberts, has been linked to another woman, socialite Eleanor Propp, New York Post reported.

The star reportedly grew close to Propp, who is in her 30s, while appearing on Broadway in `That Championship Season`.

The actor was previously married to Camelia Kath, the mother of his daughter Sarah, and Elizabeth Winn.

He was also engaged to Roberts, who dumped him just three days before their planned wedding in 1991, and fled to Ireland.
