Nicole 'Snooki' Polizzi hasn't slept ''a wink'' since giving birth to her daughter.

The former 'Jersey Shore' star - who welcomed her second child Giovanna Marie with her fiance Jionni LaValle yesterday(26.09.14) - confessed she is yet to get any rest as she is too busy looking after the newborn and the couple's two-year-old son Lorenzo.

She wrote on her Twitter account, along with a poignant quote about motherhood: ''Absolutely love being a mother to two kids! Haven't gotten a wink of sleep taking care of & staring at my daughter (sic).

''When life gets hard and you feel all alone, remember you mean the world to somebody and that somebody calls you mom,''

The 26-year-old star first shared the news she had given birth on the social media site yesterday.

She said: ''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 (sic).''

Her best friend and former co-star Jenni 'JWoww' Farley - who welcomed her daughter Meilani into the world two months ago - has already been to visit her pal and the new arrival.

Posting a picture on her website of her visit to the hospital, with Snooki cradling the baby in her arms, she wrote: ''My best friend gave birth to a gorgeous baby girl .... Giovanna is a stunning 6.7lb perfect angel!(sic)''
