Kiefer Sutherland clearly likes a drink. The '24' star already has a string of DUI convictions under his belt.

But we have to take our hats off to his latest session that began at seven o'clock in the morning.

Which isn't as bad as it sounds. After finishing up a shoot for the smash hit TV series, Kiefer and some of the crew members popped into The Spot in San Pedro, California for a celebratory tipple.

We say tipple, we mean full-on drinking sesh. An employee told TMZ that Kiefer was happily knocking back the scotch and Cokes but also bought drinks for the 30 other people at the bar.

Apparently no food was included in the bar tab, but between them the crew managed to rack up $500 worth of booze from 7am to 1pm.

And we're guessing Kiefer was feeling a little merry when he left... leaving a $200 tip.

Thankfully though, Kiefer seems to have learnt from his previous indiscretions and responsibly used a designated driver.

Kiefer isn't the only star to enjoy a boozy night out. Unfortunately, there's always a photographer waiting for the tired and emotional celebs...
