LaValle's email address was used for an account on the extramarital-affair website Ashley Madison, which might indicate he's been unfaithful or has at least attempted to cheat on the Snooki & Jwoww star, Us Weeklyreported.
Last week, hackers leaked stolen information of more than 37 million Ashley Madison subscribers, who would most likely create accounts on the website to connect with married men or women and set up affairs.
The Real Housewives of New York City star Kristen Taekman's husband, Josh, reportedly insists his email address was used for an account on Ashley Madison but it didn't belong to him, so maybe LaValle is in the same position. A representative for either Polizzi or LaValle has yet to comment.
LaValle joins many men in question such as Louisiana GOP executive director Jason Dore and former 19 Kids & Counting star Josh Duggar, who actually admitted infidelity and further confessed to having a porn addiction. Duggar's wife Anna, however, reportedly has no desire to divorce him.
Polizzi, 27, addressed cheating rumors in January surrounding LaValle, 28, according to Us.
"My man ain't goin' nowhere #shady," the former Jersey Shore star tweeted following a report LaValle had flirted and exchanged numbers while out with a woman in Florida.
Polizzi and LaValle wed in November 2014 and have two children together: Lorenzo, 3, and Giovanna, 11 months.
The Ashley Madison hack is still under investigation by the Toronto Police Department after two suicides were potentially linked to the leak.
