Nicole 'Snooki' Polizzi insists Jionni LaValle is one of the ''most loyal souls'' she knows.

The 27-year-old reality TV star took to Instagram to defend her husband on Tuesday (25.08.15) amid rumours he set up an Ashley Madison account to order to meet other women, and believes he ''would never cheat'' on her.

Alongside a photograph of them dancing on their wedding day, the former 'Jersey Shore' star wrote: ''Jionni is the the most humble, respectful, and most loyal souls I know. I mean hello, that's why I married him. He's a stand up guy who loves his family more than anything in this world.

''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.

''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. Jionni is a good guy and doesn't need his name being tarnished. Nor does our family. We did nothing wrong to deserve this. So with all of this said, I love you babe. And even though I'm a pain in you're a**, I know you would never cheat on me. Especially on a lame a** website (sic).''

The couple, who have two children, Lorenzo, two and Giovanna, 11 months, got married last November after more than three years of dating.
