Chris Brown Explosive Fight with Karrueche ... After Nightclub

Exclusive Details

update_graphic_red_bar8:35 AM PT -- A police car pulled up outside Karrueche's house early this morning while Chris was there. Law enforcement sources tell us someone called cops to complain about the noise Chris and co. were making at her door.

We're told officers spoke to Chris and Karrueche, but there was no evidence of a crime ... so no tickets, no arrests.

update_grey_gray_barChris Brown's attempted reunion with Karrueche Tran last night did not end well -- with the singer BANGING on KT's front door after she kicked him out of her SUV. 

We're told the drama started INSIDE Playhouse nightclub ... when Chris got the V.I.P. table next to the one Karrueche was at. 

We're told KT was PISSED and left the club ... and Brown followed ... eventually weaseling his way into her SUV.  

Our sources connected to Karrueche say KT did NOT want him inside -- and dropped him off with his friends a short time later. 

Which is why she was even more upset when he showed up on her doorstep around 3:30 AM -- banging and yelling, clearly trying to get KT to open up. 

Tran ultimately left her home -- and went to the famous Norm's Diner.  Brown showed up a short time later. 

Once inside, we're told they began to argue and it escalated into a full-blown shouting match. Eventually, Karrueche left the restaurant and returned home -- without Chris. 

Bottom line -- don't expect a reconciliation any time soon.
