LYNWOOD, Calif. -- One day down, 22 to go.

Paris Hilton's lawyer told reporters Monday that the hotel heiress is doing well after spending her first night in solitary confinement at a Los Angeles County jail.

"She's using this time to reflect on her life, to see what she can do to make the world better and hopefully, in my opinion, to change the attitudes that exist about her among many people," Hutton said.

Hilton is serving 23 days of a 45-day jail sentence for violating probation in an alcohol-related reckless driving case. She checked into the Century Regional Detention Facility in Lynwood at about 11:30 p.m. Sunday.

The Hollywood socialite was sent off to her jail term with a swift kick in the pants earlier in the evening, as MTV Movie Awards host Sarah Silverman made crude jokes about Hilton.

A clearly unamused Hilton was sitting stone-faced in the audience as Silverman joked that the jail's guards would be painting the cell bars to look like a certain part of the male anatomy to make her more comfortable during her stay.

Just before that, Silverman made it a point to announce that Hilton was soon going to jail, and the audience erupted in applause and laughter.

Housed in a 12-by-8 foot cell in a special unit away from other inmates, Hilton was doing well under the circumstances, Hutton said. She is is spending 23 hours a day in a solitary cell.

Hutton said Hilton is "being punished because of her celebrity."

But being a celebrity doesn't appear to be a plus for Hilton in jail.

On Saturday, Susannah Johnson, a former inmate, told reporters inmates are upset because they believe jail officials are making room for the starlet at the expense of other inmates at the already-crowded 2,200-bed jail.

Johnson, who served one day in the facility, said Hilton should just "shut her mouth and do the time."

A sheriff's spokesman said that so far, Hilton is being cooperative and is easy to work with.

Hilton was issued an orange top and pants for her stay in jail. But Madame Tussaud's Wax Museum in New York has a different take on Hilton's prison wear. On Monday the museum unveiled a new wax figure of the socialite wearing a "jail bird" outfit with black and white stripes, striking a pose.
