It was party time Saturday in New Jersey. Jionni LaVelle's parents opened up their East Hanover home to celebrate their son's engagement to Nicole 'Snooki' Polizzi and their expectant baby.

The happy young couple was joined by their Jersey Shore castmate, Snook's best friend JWoww, and Snooki's parents, Andy and Helen Polizzi. Mama Snooki arrived carrying a huge bunch of balloons.

Snooki and Jionni haven't yet announced a wedding date.  Their baby is due late summer.
