Things got real backstage at an old school reunion concert when Dru Hill's Sisqo squared off with Kyle from Jagged Edge. A video surfaced online of the two shoving each other into walls and getting put in headlocks, but there are no clues into what sparked the fight. 

Back in June, Jagged Edge stopped by The Breakfast Club, where Kyle opened up about a past incident with Sisqo. Group member Brian Casey explained that back in the day they bumped into Sisqo getting off an elevator and Kyle remarked, "What up?," while the "Thong Song" rapper kept walking. When questioned about staying quiet, Sisqo claimed he was sleepy, and Kyle replied back by saying, "Well, stay asleep, b*tch!"

Seems like tension has been brewing for a while, and it reached the surface on the tour. Check out video of the fight in the above slide and let us know what you think.
