Kiefer Sutherland will be serving

his just-begun 48-day jail stint in one stretch, a spokesperson for the lock-up tells People, saying, "There's no way he's getting out early, unless a judge orders otherwise, which is unlikely." The same jail rep describes the 24 star as a "model prisoner," adding, "He's not happy to be here, but you can tell from his demeanor that he's sorry and takes responsibility for what he's done." Sutherland, says the weekly, spent his first full day behind bars folding laundry, and has also been assigned to serve meals to the other inmates - one of whom was recently pinched for the attempted murder of four people. Um, if that guy asks for extra napkins, give them to him!
