Beyonce caught in the middle of fight at MTV VMA after party

Beyonce found herself stuck in the middle of a celebrity smack down at the MTV VMA after party on Monday night.

Music mogul Sean ‘Diddy’ Combs’ allegedly got into a fight with a partygoer who was dancing “too close to him” and his singer girlfriend Cassie at the event at the Dream Hotel’s PH-D Rooftop.

Things quickly escalated and became physical, with Beyonce screaming “stop, stop” while Jay Z reportedly got in the middle in an attempt to calm the situation and get his wife Beyonce out the way.

A source told the New York Daily News: “Diddy got in a fight with someone partying too close to him and his girlfriend Cassie.

“‘It was mayhem. Beyoncé was yelling to stop and Jay Z was separating people and getting people away from Bey.”

Apparently the ruckus subsided after about 90 seconds of shoving and bottle-breaking at around 1:30 a.m.

“We were all dancing and the fight breaks out, and it happened so quickly and bottles were crashing everywhere, and everyone was screaming. People got pushed into bottles,” another guest tells us.

“Then Diddy got up, took the mic and said ‘It’s all cool! Ya’ll keep having fun! It’s no big deal, it’s over.’ ”

Witnessing the brawl were Jamie Foxx, Pharrell, Will.i.am, Russell Simmons and Busta Rhymes, who wisely came with burly bodyguards.

Pharrell then made his way next door to No. 8, where he “arrived with an amazing crew of beautiful people,” a spy says, then had a dance-off with Jennifer Hudson.
