DMX Botched Comeback Tour — $630,000 Lawsuit DISMISSED

just caught a $630,000 break — our sources has learned, a booking agency has dismissed its enormous lawsuit against the rapper over a botched 2011 comeback tour.

our sources broke the story … an agency called Heavy Rotation sued DMX in March claiming it struck an exclusive year-long deal with DMX in 2011 to book a string of comeback concerts — but the rapper was a pain in the ass to deal with … and torpedoed the entire tour.

HR said it lost nearly $750,000 on the deal gone bad.

But the booking agency appears to have had a change of heart — because HR has voluntarily dismissed the lawsuit.

It”s unclear why — calls to both sides weren”t returned — but either way, it”s good news for X.
