“We can officially confirm that Nicole “Snooki” Polizzi is pregnant and engaged to her boyfriend Jionni LaValle,” her spokesperson tells PEOPLE. “Nicole is thrilled to finally be able to share her happy news with her fans.”

But what does the formerly hard-partying reality star’s big news mean for her future on Jersey Shore?

“No decision has been made yet on a sixth season of Jersey Shore,” an MTV spokesperson tells PEOPLE.

“We wish Nicole a healthy and happy pregnancy and congratulate her on her engagement,” the spokesperson added. “We support her as she starts this new chapter of her life.”

A spinoff series featuring Polizzi and Jenni “JWoww” Farley is still happening, a source tells PEOPLE. Snooki’s pregnancy and engagement to Jionni LaValle will not change the creative focus of the show, which will revolve around the girls’ friendship and lives as roommates, according to the source.
