The selling point of the VH1 reality show “Mob Wives” was its authenticity: a group of Staten Island women with mobster husbands and a tough-girl penchant for chardonnay, omertà and a hot temper.

The show has been in reruns for three years, but one of its stars, Drita D’Avanzo, 43 — wife of reputed mobster Lee D’Avanzo, 50 — has managed to keep herself in the spotlight by engaging in fistfights and social media beefs.

Now, she can add a drug arrest to her street cred.

On Thursday night, she and Mr. D’Avanzo were arrested in a police raid on their home on Staten Island, during which officers seized two loaded handguns from the house, along with more than a pound of marijuana and modest amounts of hydrocodone and Xanax pills, the police said.

At her arraignment in a Staten Island courthouse on Friday afternoon, Ms. D’Avanzo lacked her usual on-camera glamour and feistiness, appearing in a plain dark winter jacket, her hair pulled back into a modest ponytail. A scruffy Mr. D’Avanzo wore a black sweatshirt.
