BEIJING, Sept. 21 (Xinhuanet) -- Hollywood socialite Paris Hilton pleaded guilty to cocaine possession and obstructing an officer in a Las Vegas court on Monday, according to media reports.

Hilton, 29, admitted that cocaine found in her purse after a traffic stop last month was hers and that she lied about it.

"I said that the purse wasn't mine to the officer, your honor," she said to the judge.

The celebrity heiress must complete a drug abuse program, pay a 2,000 U.S. dollar fine and serve 200 hours of community service.

Besides, she was also given a one-year suspended sentence and warned that any new arrests in Las Vegas would result in her going to jail.

The plea agreement does not require Hilton to be assigned a probation officer, meaning she won't have to report to anyone.
