Rick Ross and Young Jeezy have been involved in a fight backstage at the BET Hip Hop Awards, reports TMZ.
The rappers are said to have "started pushing and shoving each other" in the parking lot at the venue last night (September 29) before bodyguards and security stepped in and the police were called.
DJ and MTV host Funkmaster Flex - who also attended the awards - first broke news of the scuffle online.
"Jeezy and Rick Ross just had words backstage!! Pushing and shoving!!!" he tweeted.
"Beef just spread to the parking lot!!!" he added minutes later, before suggesting that a firearm may have been involved.
"Shortly after 7:15 pm Saturday, a fight broke out in the parking lot at the Atlanta Civic Centre between two groups," confirmed a spokesperson for the Atlanta Police Department.
"Officers on scene responded to break up the fight and used OC spray in the process. Individuals fled the scene. There were no arrests or reports of serious injuries. Reports of shots fired appear to be untrue."
The feud between Rick Ross - who recently played a show at London's Wembley Arena - and Young Jeezy dates back to August 2010, when Jeezy released the track 'Death B4 Dishonor'. The song contains lines that were supposedly 'disses' directed toward Ross, including comments about the rapper's Black Mafia Family crew credentials.
Jeezy went on to deny reports that the track referenced Ross, telling MTV News: "It's not a diss... I think sometimes people can read into things too deep. They trippin', man... Basically, if homie takes that as a diss, he's insecure."
MTV News reports that Ross's protégé Gunplay was also involved in a fight with members of 50 Cent's G-Unit. Both scuffles are alleged to have taken place while A Tribe Called Quest, Missy Elliott and Busta Rhymes paid tribute to fallen music mogul Chris Lighty.
Police have yet to release the names of those involved in either altercation.
