Karrueche Tran -- I'm Single Again Baby!

Karrueche Tran wanted to make a statement Wednesday and the statement she made ... Chris Brown is in her rear view mirror and she's back on the market.

Chris' non-baby mama and a few of her friends who also haven't been knocked up by him hit up the clubs in Hollywood. Karrueche, Christina Milian and a few other chicks went to Hyde and then moved over to Warwick.

Our photog had plenty of questions about Chris' 9-month-old baby girl -- something Karrueche didn't know about until our story broke Tuesday -- but all she did was giggle.

Gentlemen, the line forms to the left ...
