Chad's been arrested for violating his probation...

TMZ got that 411:

... a warrant had been issued for Johnson's arrest earlier this month after he failed to report to his probation officer on 2 occasions AND failed to show proof of enrollment in a domestic violence education class.

Johnson's probation stemmed from his domestic violence conviction involving ex-wife Evelyn Lozada last year.

35-year-old Johnson appeared in a Broward County courtroom over his alleged probation violation -- and moments ago, the judge determined Chad WAS in violation and ordered him to be arrested and jailed.

Really Chad? You didn't want to enroll to a domestic violence class or see your probation officer? The funny thing is that he had time to buy K. Michelle a monkey, but he can't get things right with his probation officer? I can't.
