Paris Hilton spent her final hours of freedom in familiar territory on Sunday, front and center at a celebrity event near Hollywood — as people cheered her upcoming incarceration.

The socialite, who is due to report to a Los Angeles jail by Tuesday to serve 23 days for driving-related probation violation, was on hand at the MTV Movie Awards, smiling stoically in the face of jokes at her expense.

The ceremony’s host, Sarah Silverman, drew loud cheers just by mentioning her upcoming date with the law.

The raunchy comedian joked that the bars of Hilton’s cell would be painted like penises to make her feel more comfortable, but noted: “I just worry that she’s going to break her teeth on those things.”

Silverman also saved some barbs for another troubled party girl, describing Lindsay Lohan as “a rude little pig.” The actress recently returned to rehab after crashing her car in Beverly Hills. Lohan was scheduled to be a presenter at the awards show, but did not make it.

A source said: “Paris hasn’t been eating at all and her parents and friends are beyond worried about her.

“She breaks down crying a lot because she just can’t deal with the reality and the pressure of everything that is happening.

But a source close to ‘The Simple Life’ star recently said that she would emerge from jail more beautiful than ever.

The insider said: “It’s going to make her more famous than ever. In jail, she’s going to get enviably skinny, and without any make-up or products her hair and skin will finally be able to breathe, so they’ll look amazing, too.

Plus she’s going to get all that street cred.”

The 26-year-old socialite was sentenced to 45 days in jail for violating the terms of the probation she received for Driving Under the Influence (DUI) but she will only serve 23 days.

Paris released a statement saying, “I am ready to face the consequences of violating probation”, and two weeks later dropped her appeal case against the sentence.

“I’m very professional and I don’t usually drink on the job, but that morning I had to have something. It was my first sex scene and thank God James Gray was directing it. He did it at the end of the shoot, so it was the last day and I was really, really comfortable with James and Joaquin.”
