The former "Jersey Shore" star gave a lengthy testimony about LaValle's loyalty on Instagram following the reports that he was linked to Ashley Madison website.
In the wake of Josh Duggar's infidelity, more men are linked to the website that allows married men to have an affair.
"This morning when I got a call from my publicist that a story was going to be printed on my husband 'allegedly' signing up on Ashley Madison, I laughed- and said lets not even comment and give the story any juice, because it couldn't be any further from the truth," Snooki captioned an Instagram pic of the couple at their November 2014 wedding.
She continued, "He's a stand up guy who loves his family more than anything in this world. The fact that the tabloids can deliberately make stories up and print things like 'Jionni LaValle ALLEGEDLY and MAY HAVE signed up on Ashley Madison' is absurd. I can see if there is proof in the story to make it legitimate, but to accuse my husband of something he had no idea about... HOW IS THAT LEGAL?"
"I really didn't even want to acknowledge this absurd story, but when my family is being bashed for no reason- mama bear is gonna say what's up," she wrote.
"So no, 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.
