Snooki has confirmed she has named her unborn baby Lorenzo.

The 'Jersey Shore' star announced that she and fiance Jionni LaValle have already decided on the moniker for their child after some of her female cast members accidentally revealed the name to reporters.

In an interview with USA Today, the reality TV stars shouted out the name of her unborn baby and Jenni 'JWoww' Farley tried to insist the brunette beauty was yet to be 100 per cent sure on a title, claiming: ''Well, it's a name she's thinking about.''

But Snooki - who is due to give birth in September - confirmed: ''No, it's done.''

The 24-year-old star - whose real name is Nicole Polizzi - has also admitted she was ''really upset'' by the low-key reaction she got from the 'Jersey Shore' cast when she announced her pregnancy.

She told the New York Daily News: ''I didn't exactly get the reaction I wanted. It actually made me really upset.

''My roommates and I joke a lot, so they kind of took it as a joke. But I take this very seriously -- this is my life.''
