Chris Brown may be working hard to get back into ex Karrueche Tran’s good books – but he’s going to have to work equally hard with her friends. The musician was filmed as he left Club PlayHouse in Hollywood last night, following ex girlfriend Karrueche closely. The brunette beauty looked stunning in a t########## dress, and walked ahead of her former beau – who she recently split from after finding out he had a secret love child. As she got into her waiting car, surrounded by photographers, Chris followed shortly behind but stalled when her friend appeared to ask him to get out.
