Police have identified a suspect in the slashing attack of "Mob Wives" Natalie Guercio's boyfriend outside a Brooklyn dance club early Sunday morning, reports the New York Post.

Rodolfo "Rudy" Lopez allegedly attacked the reality TV star's beau, London Rene, 37, with a box cutter outside Club Output. Rene suffered multiple gashes on his face, stomach and arm.

The worst injury was a huge wound on the right side of his face. Police say he is lucky to be alive.

Rene was taken to the hospital by ambulance.

TMZ reports Guercio was standing beside Rene during the attack.

Guercio had posted pictures of Rene being treated for his injuries at Woodhull Hospital on Instagram, writing, "London was just slashed in the face" and that he received more than "250 stitches."

Lopez, who is believed to be an acquaintance of Rene, fled the scene following the attack. He is still at large. He is described as 5-foot-9, 200-pounds and has short black hair, according to police.

Guercio and Rene are no strangers to nightclub high jinks and barroom brawls.

In March, Guercio was at Delilah's Gentleman's Club in Philadelphia to judge the Entertainer of the Year when she got into a fight with one of the club's bouncers who punched her in the face. Police were called, but she did not press charges.

December 2013, Rene and Guercio allegedly started a brawl at the "Mob Wives" New York City Premiere Party held at SoHo club Greenhouse. It started when Rene got into a verbal argument with another partygoer. Guercio was investigated by cops for allegedly cracking a booze bottle over another woman's head.

In the summer of 2013, Guercio was caught on camera locking lips with married music producer Ryan Banks at a Philadelphia nightclub. Banks claims to have hooked-up with her more than once.
