A federal judge Friday blocked rapper Lil' Kim from performing at a music festival on the Caribbean island of St. Kitts later this month.

The performer, whose real name is Kimberly Jones, is barred from leaving the United States as part of a bail agreement in a shooting case.

Judge Gerard Lynch scolded Jones - known for her revealing outfits and risque lyrics - for having agreed in May to perform at the St. Kitts Music Festival. She had surrendered her passport in April after she was charged with lying to a grand jury about a 2001 shootout between rival rap groups at a New York hip-hop radio station.

Lawyer Mel Sachs argued Jones was not a flight risk: "Your Honor, this is a well-known performer," he said.

"Tell that to Roman Polanski," the judge replied, referring to the Oscar-winning director who fled the United States after he was charged in 1977 with having sex with a 13-year-old girl.

"Just because you're a celebrity doesn't mean you don't jump bail and leave the country."

Lil' Kim, was to perform at the music festival June 26 along with Ginuwine and Busta Rhymes. Sachs told reporters she would have been paid $35,000, and now will have to pay a penalty.
