LaValle, 27, is the latest celebrity to be exposed as probably having used the site, which facilitates extramarital affairs. Other stars whose information was connected to the site include Josh Duggar and Josh Taekman, husband of Real Housewives of New York City star Kristen Taekman.
LaValle and Snooki, 28, were married last November and have two children together: Lorenzo, who turns 3 on Wednesday, and Giovanna, 10 months. Reports that LaValle may have cheated or was looking to cheat have dogged the couple for months, but Snooki has adamantly denied them.
Earlier, representatives for Snooki told People that the couple is not addressing the Ashley Madison rumor. The reality star, however, eventually took to Instagram to post a touching photo of her and her husband that included a lengthy caption defending his and her family's honor. Take a look:
Meanwhile, the former Jersey Shore star has spoken out about Josh Duggar's wife Anna's decision to stick by him, despite both his child molestation scandal and admission of infidelity.
"He called himself a hypocrite, and he said, 'I'm ashamed of myself,'" Polizzi said on Tuesday's episode of her Naturally Nicole podcast. "His wife is still standing by him. Like, what the f--- is wrong with you? Like, what are you doing?"
Last week, hackers released the personal data of more than 37 million Ashley Madison subscribers. The Toronto Police Department is investigating the hack, amid speculation that two suicides have been tied to the leak.
