Kiefer Sutherland Dating Beauty Magazine Style Editor

Kiefer Sutherland is enjoying a new romance.

The '24' actor - who recently served time in prison for drink-driving offenses - has been dating Allure magazine style director Siobhan Bonnouvrier for two months and friends say it is getting serious.

One said: "Jail was the best thing that ever happened to Kiefer. It scared him straight."

"Kiefer's finally grown up - and part of his turnaround is due to Siobhan. Siobhan is an amazing woman, and she's transformed Kiefer in just a few short weeks. She isn't the least bit fazed by Kiefer's fame or by his wild past, and the relationship has blossomed."

Although the couple are yet to discuss marriage, they are both said to be keen to commit to the relationship.

The friend added to the National Enquirer magazine: "It's a little premature to talk marriage. They both are looking for a long-term, serious commitment."

Kiefer started his 48-day prison sentence in December after he was arrested for driving under the influence (DUI) in September while on probation for another drink-driving offense in 2004.
