UPDATE: Fabolous Bashes Ray J's Fight Claims, "All Of That Sh*t Is Lies"

Brooklyn rapper Fablous has come forward to address accusations made by R&B singer Ray J alleging they got into a physical altercation over the weekend in Las Vegas.

Calling in to New York's DJ Clue during his Power 105.1 radio show, Loso killed the day's hype.

"Who called in, Tupac?" Fab said sarcastically referring to Ray J's initial Monday morning rant. "Tupac called in? That wasn't Ray J. You can't be serious. That wasn't Ray J. That wasn't him. That wasn't Willy Norwood Jr. That wasn't him. That wasn't Brandy brother...It was no fight, it was no swing -- This whole story that he made up, that Tupac rant about him swinging on somebody and all of that sh*t is all lies. It's all, high on coke, on that Whitney. That's all on that Whitney last night. Ain't no swings take place. You can ask the Money Team. The Money Team was standing right there. Ask the Money Team that hes probably the water boy for -- There's nothing to squash. We can progress in our own ways. He can go his way and I can go my way. He can continue playing the piano at Floyd's crib if he wants and I'll continue to do what I do and he can continue to do concerts in n*ggas living rooms all he wants." (Power 105.1)

Monday morning, Ray J called into the Power 105.1 "Breakfast Club" show to give his take on what went down.

"I'ma smack you up again, fool! 'Ray J got beat up?' I'll sock that n*gga in the face, my n*gga," Ray J told DJ Envy, Angela Yee and Charlamagne Tha God. "All I'm saying is if you got Fab's number, tell that n*gga to send you a picture of his face right now...I'm with the Money Team right now. I swear to God he's running from me right now...[After I hit him,] he fell back because he's a sucker -- Fab ain't no comedian. My homie saved his life when he was in LA so how dare you even speak disrespectful to me. So when I seen him, I was with Floyd [Mayweather] and 50 [Cent] and he tried to say 'Don't touch me' and I [punched] that n*gga -- If you disrespect me, don't come to the West Coast. So he in Las Vegas and he tried to disrespect me?" ("The Breakfast Club")

Rumors of the one-on-one fight hit the Internet early Monday.

It seems Floyd Mayweather and Victor Ortiz wasn't the only two shooting the fair one on Saturday night. According to various fans, R&B singer Ray J and Brooklyn rapper Fabolous got into a fight this weekend backstage at a concert. The hear say first started on Twitter after a fan wrote: "Just saw Ray J and Fabolous throw blows backstage at the concert in Vegas," while another tweets, "So @RayJ just punched @myfabolouslife about some dumb stuff but Fab whooped his a** backstage." Unlike the Mayweather bout, fans won't get to see the alleged fight on video. Reports have it that security guards forced all onlookers to delete any footage. (Singersroom)

Fab took to Twitter Saturday (September 17) to poke fun at Ray J.

"N*gga Ray J doin a concert in his living room... Lmaoooooo," he tweeted Saturday.

"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!!"

"Get it..? Ray J concert in the living room!! *Lil Wayne voice*"

"Jus ran into my n*gga @RayJ at @iamdiddy dinner.. He told me & @KevinHart4real that it was a f*cked up edit & b*tches was there!!" (Fabolous' Twitter)
