Rick Ross is entering the boxing arena.

The rapper is set to walk Manny Pacquiao to the ring for his May 7 fight with Shane Mosley.

"I'm walking homie to the ring..MAYBACH7TH!! PACQUIAO SELFMADE!!" Ross tweeted.

According to published reports, Ross -- a former correctional officer -- has a long-standing feud with fellow rapper 50 Cent, who happens to be a friend and business partner of Pacquiao's biggest rival, Floyd Mayweather Jr.

Ross isn't the first rapper to have walked a boxer to the ring. Redman and Method Man previously walked out with Roy Jones Jr., while Nelly has accompanied Cory Spinks, Tupac joined Mike Tyson, and Diddy entered with Naseem Hamed.

Ross is currently featured on Estelle's new single, "Break My Heart," and Pill's "Pacman."
