Snooki Polizzi and Jionni LaValle's Ashley Madison scandal was slammed by a former "Jersey Shore" co-star. According to a report from OK! Magazine, ex-MTV reality star Sammi "Sweetheart" Giancola blasted cheating rumors that have been dragging her two friends.

The model and TV personality was interviewed at OK! Magazine's Runway Ready New York Fashion Week party at HAUS last September 15. At the event, Sammi Giancola shut down infidelity allegations and defended Snooki Polizzi and Jionni LaValle.

"They're happily married," she said. "They are a beautiful couple... I don't see Jionni doing that at all."

The 28-year-old then diverted the issue away from the Ashley Madison controversy, which came after the leak of a list of alleged account holders from the infamous cheating site. Instead, Sammi Giancola talked about the upcoming wedding of another "Jersey Shore" couple, Jenni "JWoww" Farley and Roger Mathews.

"Jenni's wedding is going to be very extravagant. It's going to be wild and it's going to be crazy," she said. "It's going to be a beautiful, gorgeous, big wedding."

According to a report from Mirror UK, Snooki Polizzi was first to defend Jionni LaValle from cheating allegations that came out last month.

"Jionni is the the most humble, respectful, and most loyal souls I know," she captioned an Instagram photo from their wedding.

"He's a stand-up guy who loves his family more than anything in this world."

"My husband didn't sign up on that website to cheat on me. Honestly, if he wanted to cheat - he would go out and do it. Not sign up on a website and pay for it," she added.

Star Pulse recently reported about how Snooki Polizzi herself sparked rumors that she and her husband are not doing fine. The former party girl turned domesticated mother-of-two was spotted several times without her wedding ring, which she later on explained.

"FYI I don't wear my wedding rings because they're too big," she clarified. "I need to resize them so I won't lose them. I'm still happily married."

"Jionni is a good guy and doesn't need his name being tarnished. Nor does our family. We did nothing wrong to deserve this," she added.
