We’ve witnessed a lot of debauchery over the years from one Kiefer Sutherland. I personally love the guy and would relish the opportunity to have one or two drinks with him, but he definitely gets carried away to the point where he’s been known to end up with his pants off in any given pub. A few years ago, things got really hairy when he was kicked out of a London strip club, racked up a $700 pre-lunch bar tab, and headbutted a fashion designer. Most notably, Kiefer screwed up big time by getting popped with his second DUI and, consquently, he served a 48-day sentence in jail.

Subsequently, Kiefer started dating Siobhan Bonnouvrier, an Allure style director who seemed really, really good for him. In fact, he stopped getting into trouble, and the two enjoyed vacations to Italy where stuff like this happened:

Unfortunately, Kiefer and Siobhan have recently ended their romance, and The Enquirer reports that his friends are now worried that Kiefer will go batsh-t crazy with the bottle again:

Kiefer Sutherland has turned the page on his three-year romance with a magazine style director — and the breakup is threatening to plunge the “24” star back into his wild, self-destructive ways, say worried friends.

The actor’s girlfriend Siobhan Bonnouvrier was a stabilizing force for the 44-year-old Hollywood hell-raiser, who served a 48-day jail sentence in 2008 stemming from a second DUI conviction and probation violation.

A short while after being freed, the twice-married star hooked up with low-key Siobhan – who kept him on the straight and narrow, say sources.

Kiefer was rudderless before Siobhan,” an insider told The ENQUIRER.

“Now with her out of the picture, pals fear he will be back to trawling bars looking for hookups and boozing.

“Kiefer does best when he’s in a committed relationship. Siobhan was great for him. She encouraged him to focus on his acting, and nearly got him to the altar.

“But ultimately he didn’t want to be tied down, so Kiefer broke things off.”

In May, the actor wrapped up his run in the Broadway play “That Championship Season” and returned to Los Angeles to work on a film version of the hit FOX series, “24.”

“Now people are taking bets on how long before he’s in trouble again with the law,” confided the insider.

“He needs a good woman to keep him straight. Friends are begging him to consider getting back with Siobhan – but for the time being, he wants to be single.

“Everyone has their fingers crossed, hoping Kiefer won’t start losing it again now that he’s on his own.”

Hopefully, Kiefer won’t go down the public boozing route again, but the man enjoys his liquor, so there’s a decent chance that he’s already there. At the very least, he should be smart enough not to get behind the wheel again after getting loaded. Like, tackling Christmas trees is all fine and dandy, but hiring a driver is absolutely necessary for the ride home. However, I think that Kiefer really learned his lesson with that second DUI, and I respect the hell out of any celebrity who doesn’t try to get out of jail time like a certain Lohan. Instead, Kiefer kept his mouth shut, put his head down, and he did his time. Now, if he can only stay out of trouble in the future.
