Though they broke up earlier this year (for the tenth time), Chris Brown still clearly has a thing for his former bottom chick Karrueche Tran. To the point where he is full out cock-blocking anyone who tries to try their hand with the young vixen. Exhibit A: Tran recently posted a picture on Instagram of her wearing an alluring black swim suit. R&B singer Marques Houston saw the flick and couldn't help but comment typing, "dizayum, look at all that booty, can't even see your face cuz that booty in the way." CB responded quickly with the hilarious quip, "Go home Roger" in reference to Houston's role on the '90s TV series "Sister, Sister."
