Jailed actor KIEFER SUTHERLAND’s 48-day spell behind bars has begun well - with sacks of fan mail.

The 24 star entered Glendale City Jail in California last week (05Dec07) after he was handed the sentence for drink driving and violating probation in September (07). And, though he’s only allowed to read two books at a time, Sutherland is not short of reading material.

A spokesman for the jail tells U.S. news show The Insider, "The guy’s been getting a ton of fan mail - easily more than 100 letters a day." Sutherland, 40, will spend his birthday (21Dec07), Christmas and New Year behind bars.
