Meek Mill's latest probation violations are going to hit him hard in the pocket book.

This week, a judge ruled Meek isn't allowed to leave the Philadelphia area until February 5th, when he will be sentenced for not telling the court about his AMA's travel and for faking a drug test.

Meek had already booked time at a 15K a week California recording studio that he's now going to have to eat. He can't take advantage of the house in LA he's renting when he's travel restricted, and, per the judge's orders, he isn't allowed to perform -- even in Philly.

Mill is especially concerned about having to miss his New Year's Las Vegas show with girlfriend Nicki Minaj, which he was going to receive 140K for.

That's not even getting into all the money he's paying to his lawyers, who are trying to keep him out of jail.

Even if he's not sentenced to prison in February, there's a good chance the judge will extend Meek's travel restriction.

That would completely cut him off from touring -- his best source of revenue.

Update: Meek Mill is also going to miss out on the chance to act in a Will Smith produced movie. He had been cast in 12 O'Clock Boys, which is about illegal dirt bike riders in Baltimore. But now he won't be able to make the shoot due to his travel restrictions.
