The well wishes are already rolling in for the happy couple; Polizzi's castmate Pauly D sent her a sweet tweet Sunday morning. "Congrats @snooki And @JLaValle !!!! I'm Officially Uncle Pauly !!! #MyMeatballHadAMeatball," he wrote.
Snooki, 24, and LaValle, whom she met at Seaside Heights hotspot Karma in 2010, first shared their happy news -- that they are engaged and set to become parents -- with Us earlier this year.
The reformed party girl admitted she knew their announcement would cause a bit of a stir among her critics.
