Welcoming the insulation from Sarah Silverman's caustic (if only somewhat witty) barbs, Paris Hilton's version of an MTV Movie Awards after-party found her checking into the Century Regional Detention Facility in Lynwood, California, shortly after 11:30 pm Sunday, to commence her three-week sentence. ( See video at In a statement to People, the sheriff's department says the celebutante "was cooperative during the [booking] process, which included being fingerprinted, photographed [and] medically screened."

Hilton, who surrendered to sheriff's deputies after frequenting MTV's kudoscast, said on that red carpet, "I'm doing OK, obviously a little scared. But I'm being strong and I'm ready to face my sentence. I hope this can be an example to other young people" [from wealthy families whose jail stints are chopped in half].

In a statement issued by her lawyer Monday morning, Hilton added, "This is an important point in my life and I need to take responsibility for my actions. In the future, I plan on taking more of an active role in the decisions I make."

Hilton will serve her time in the "special needs" unit of two-person cells reserved for celebs and other high-profile inmates. Thus far, she has no bunk mate, though Lindsay, you have to admit, has been trying her darnedest.

UPDATE: Attorney Richard A. Hutton tells People that while his client is allowed an hour of recreation each day, Paris "is in isolation for 23 of the 24 [other] hours. And ask yourself, for what? For driving on a suspended license as a probation violation. This is unjust, unfair, and she really is, unfortunately, a victim of a system that we pride so much on being fair. But for Paris Hilton it is not." That said, Hutton notes, "She's doing very well under the circumstances. The staff here have reported that she has been gracious, polite, and thankful for helping her."
