Selena Gomez and Justin Bieber engaged in a nasty public row after the former Disney star allegedly call the Canadian pop singer a "drug addict," reports say. Moreover, Selena Gomez further annoyed Bieber when she accused the singer of being unfaithful to her-after finding out the casual relationship of Bieber with a girl named Kristina. The allegations are not far from the evidence; just recently, Bieber was found in notorious brothel in Brazil in which the 19 year old Canadian singer took home a prostitute for some 'fun.'

In revealed text messages, Justin Bieber called Selena a "talentless p***y" as he was enraged by the latter's calling out on him on his alleged drug habit. The couple has been on and off in terms of their relationship, but this row might seem to be the nastiest. In a similar incident, the enraged Canadian singer kept sending Selena aroused photos of his private parts after uttering words such as "F**K YOU!!!!! I need to grow up? HA ok! Enjoy life with OUT ME B***H" and "Can't hear you over my cash, babe! You're only famous cuz of me. You know it. I know. Everybody knows. Bye. ... Go f**k someone else. Keep that talentless p***y away from me!"

While things have spiraled out to something nasty, it seems that Gomez is having the last laugh. During an after-party for the actress' flick "Rudderless," Gomez was seen canoodling a mysterious blond man. One onlooker reported "She went right up to him really early on in the evening," and that the two looked comfortable with each other. Moreover, sources say that Gomez even placed her hands comfortably on the hunky man's legs as they sipped cocktails together. However, a reliable source from Gomez's camp revealed that the two were just good friends.

Even if that were the case, Selena Gomez has been seen enjoying herself in the Sundance Film Festival, looking almost unfazed about the nasty incident that occurred between her ex flame, Justin Bieber.

Meanwhile, her Canadian ex boyfriend has been seen squandering his money in strip clubs. The rumors on the drug use of the singer are yet to be proven true by authorities.
