RAY J & FABOLOUS THROW BOWS BACKSTAGE AT A CONCERT!

While Floyd Mayweather was boxing his way to victory on Saturday night, Fabolous and Ray J apparently had their own fight going on backstage at a concert.

Twitter went crazy over the weekend when several Tweeters reported that Fab and Ray had got into a scuffle with each other at Fabolous' concert. Some concert-goers tweeted the first sighting of fists flying, including: "Just saw Ray J and Fabolous throw blows backstage at the concert in Vegas," and "So @RayJ just punched @myfabolouslife about some dumb stuff but Fab whooped his a** backstage."

However, anyone hoping to catch a glimpse of the alleged fight may be disappointed because concert-goers were forced to delete any footage by a security guard.

The beef between Ray and Fab started a few days ago when Fab took shots at Ray on his Twitter, writing: "N**ga Ray J doin a concert in his living room," and "Nah but Floyd [Mayweather] 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."

It then escalated when Ray's friend retaliated, saying: "Check dis out keep playn with the homie @RayJ u b**ch a** n**gas ant b able 2 move around on PIRU."

LMFAO! THAT SH!T FAB SAID IS FUNNY! BUT THAT'S THAT PUNCH YOU IN THE MOUTH WHEN I SEE YOU SH!T!
