The rapper violated the terms of his parole in a six-year-old drug and gun case earlier this month (Dec15) by repeatedly changing his court-approved travel schedule, and accompanying Nicki to the American Music Awards in Los Angeles in November (15) without the permission of his probation officer.

A Philadelphia judge set sentencing for February (16), while ordering Meek not to perform any shows or leave Pennsylvania.

As a result, the hip-hop star has been left with no choice but to scrap a show in Sin City on Thursday (31Dec15).

"Following the recent Pennsylvania court ruling, Meek Mill's scheduled New Year's Eve performance at Drai's Nightclub at The Cromwell in Las Vegas has been postponed until further notice," a representative for the club tells "Headliner Nicki Minaj, who is also slated to appear that evening, will perform as scheduled."

Nicki had tried to vouch for her man in a bid to keep him out of jail by testifying in his defence during the recent probation hearing, during which she insisted he is a new man.

"He's not perfect but I can't believe how much he's changed," she said, before telling the court she plans to help her boyfriend get organised and fulfil his community service requirements.

Meek also took the stand and broke down as he pleaded for leniency.

"I'm not a gangsta," he declared. "I'm not a criminal... I have my queen, Nicki, now. I'm trying to do better and feel like I can be the best rapper out there."

It won't be a fun New Year for Meek as not only will he have to celebrate without his girlfriend, but the threat of jail time hangs over him if the judge overseeing his case decides to make an example of him.
