What should have been a happy celebration took a violent turn last night when a brutal fight broke out at the NYC premiere party for the new season of Mob Wives: New Blood. Wetpaint Entertainment spoke to a source at the event, who confirms that new cast member Natalie Guercio got into an argument that quickly turned physical, leading to one person being taken to the hospital.

The private event was held at Greenhouse following a screening of the VH1 show’s premiere. According to our source, Natalie and another female partygoer got into a verbal altercation, which led to the reality star smashing a bottle over the woman’s head.

The mystery woman was then taken to the hospital where she required stitches. She did not, however, press charges against Natalie. It’s believed that the unnamed woman is related to fellow Mob Wives: New Blood star Renee Graziano.

Although no one else is said to have been seriously injured, TMZ reports that at one point following the initial bottle-smashing, more than 10 people were involved.
