A man accused of slashing the face of a “Mob Wives” star’s boyfriend has turned himself in, police said.

Rodolfo “Rudy” Lopez — who allegedly sliced “Mob Wife” Natalie Guercio’s beau on Sunday in Brooklyn — was jolted after catching a glimpse of himself on a TV news segment, a law-enforcement source said.

Lopez, 35, of Jersey City, surrendered to cops at the 94th Precinct in Williamsburg on Tuesday. He is charged with felony assault, reckless endangerment and criminal possession of a weapon.

Lopez allegedly slashed the curvy reality star’s boyfriend, London Rene, 37, outside the trendy Club Output on Wythe Avenue near North 12th Street, leaving him with gashes requiring more than 250 stitches.

On Sunday, Guercio posted pictures of Rene’s bloody face at Woodhull Hospital on social media.

Lopez and Rene are believed to be acquaintances.
