Nicole "Snooki" Polizzi and her fiance Jionni LaValle have welcomed their second child into the world, a baby girl.

"So happy to let you know we had our beautiful daughter this morning Giovanna Marie LaValle. 6.7 lbs, full head of black hair & perfect," Polizzi tweeted Friday followed by two hearts and a smiley face.

The Snooki & JWoww and former Jersey Shore star, 26, already has a two-year-old son Lorenzo with LaValle.

The couple revealed they were expecting a baby girl in early May, just one month after confirming the second pregnancy.

Polizzi and LaValle, also 26, reportedly still intend to get married before the end of the year, as they had been planning a fall wedding. The pair broke the news of their engagement and the first pregnancy in March 2012.

Polizzi's co-star and best friend Jenni "JWoww" Farley and her fiance Roger Mathews also welcomed a baby girl, Meilani, in July. Polizzi had accepted the role of godmother to the child.
