It went down Feb. 24 at the Grand Marshal's Ball — a Mardi Gras event in Fairley's hometown of Mobile, Alabama — where Nick was the Grand Marshal and Jagged Edge was the featured entertainment.
But when JE took the stage, all hell broke loose because the 6'4", 300-pound defensive lineman refused to get off … and the singers felt he was disrespecting them.
Security was called in … but Fairley still wouldn't leave. You can hear people yelling at Fairley to go. At one point, a frustrated Jagged Edge says, "You want the mic? You can have this show my n**ga."
JE cut the session short and a full scale melee almost erupted when members of Fairley's family stormed the stage … one yelled into the mic, "F**k Jagged Edge!"
BTW — Nick JUST re-signed with the Saints for a reported $30 million … so all that rushing seems to be paying off. Just keep it on the field big fella.
