Kiefer Sutherland outside Ed Sullivan Theatre for the 'Late Show With David Letterman'. New York City, USA - 07.08.08

The 24 star was sentenced to 48 days in jail after he was caught driving under the influence in Los Angeles last September (07).

He subsequently spent his 41st birthday, Christmas and New Year's Eve behind bars.

Sutherland has now broken his silence about his time behind bars, joking, "I dropped the soap!"

He continues: "I actually dropped the soap. I remember looking down at it and then I looked around and thought: 'Soap is over-rated... I'm done with this shower!'"
