According to The New York Daily News, Big Ang "tried to attack" Graziano while filming at Ainsworth Park in New York. "Big Ang went psycho," a source told the newspaper. "Renee literally ran out of the place."

"I would run out, too - (Big Ang) is scary!", the source continued about the reported fight. "She was screaming at (cast member) Gravano and Renee, calling them 'rats'." No one was exactly sure what sparked Big Ang's anger, but only D'avanzo could calm her down, reportedly.

"It was a shock because Big Ang is so sweet - she's really not a fighter. Renee must have really upset her. Karen got in the way, and she was tossed like a feather by Ang."

Mob Wives will be back in December.
