Sources told Usmagazine.com the fight at My House broke out after Francis accidentally hit Brody's girlfriend, model Jayde Nicole.
"Francis reached out to grab Brody and ended up hitting Jayde in the head," one source said. "Brody defended her and it turned into a massive fight."
"Security dragged Francis out. Joe hit Jayde and was making death threats against Brody. Brody filed a police report," added another insider.
However, Francis said in an exclusive statement to Usmagazine.com that the whole thing was a misunderstanding.
"I went to give Brody a hug and I guess my elbow accidentally bumped the back of his girlfriend's head. I didn't even know that happened until this morning. I was shocked. Brody and I are longtime friends," Francis said. "I think he was a little drunk and he started yelling at me, but it's all OK. He was angry. Brody's girlfriend is the type of girl that gets off creating drama. She was winding him up. There was no physical altercation. I would never threaten to beat him up and I would never get in a fight. The whole thing was 20 seconds."
