Puddle of Mudd singer Wes Scantlin is keeping his lawyer busy ... because TMZ has learned, he just got arrested AGAIN last night ... stemming from an issue with his cocaine case.
Law enforcement tells TMZ, Scantlin was pulled over in Hollywood around 11:30pm Tuesday night for speeding ... and when police ran his info, they discovered two warrants out for his arrest.
Scantlin was arrested on the scene and taken to a nearby police station, where he was booked. He was released a few hours later on $11,176 bail.
We're told the warrants stemmed from two separate cases -- one for driving on a suspended license and one for his recent cocaine bust. It's unclear what triggered the warrants ... but it's likely he simply blew off court dates.
As we reported, Scantlin was arrested for coke possession in January 2012. He was arrested again in September at an airport in Austin, TX, after allegedly becoming drunkenly combative with a flight attendant. The airport case was dropped.
Wesley's attorney had no comment.
