Paris Hilton was jubilant when she was released from jail last night, according to a TMZ.com report.

But here's the kicker: According to law enforcement officials, Paris lost 10 pounds in prison! That's right, folks. It's time to prepare yourself for Paris's Prison Diet (how I lost 10 pounds in 23 days) book.

Thinking ahead, it may not be such a great idea to slap Nicole Richie in jail. If she loses ten pounds, she's gonna disappear. Better cop a plea, Nic.
