The boxing match between Floyd Mayweather and Victor Ortiz wasn't the only fight in Las Vegas last weekend. According to reports, Ray J got into a tussle with Fabolous Saturday night (Sept. 17) over comments Loso made about him on Twitter.

Ray J called into Power 105's The Breakfast Club this morning to tell his side of what happened that night. In his expletive-laced tirade, the R&B crooner was unhappy with Fab's tweet about his appearance on HBO's Floyd Mayweather and Victor Ortiz documentary '24/7,' in which he wrote, "Nah but Floyd saying we havin a concert in my living room & the camera cuts to Ray J singing "One Wish" on the piano had me in tears!!" The two reportedly went toe-to-toe outside of the Palms Casino in Sin City, where Ray J claims he "socked that n---a in the face." The singer was arrested but was later released.

Ray J continued his barrage of profanity against Fabolous on the show calling him a broke-ass rapper and promising that Fabo will apologize for his actions. Meanwhile, Fab seems not too worried about Ray J's threats. "These n---as thinking I fell off... Ooooh I needed that!!!" he tweeted this morning.

In Fabolous defense, the rapper is infamous on Twitter for poking fun at rappers and celebrities. However, in this case, we don't think Ray J has a sense a humor. Hopefully, this beef doesn't escalate into more violence. You can hear the censored audio below.
