\"Jersey Shore\" reality TV star Nicole \"Snooki\" Polizzi gave birth to a 6-pound 5-ounce baby boy and is \"so in love\" with him, she said on Twitter. \"I am SO IN LOVE with my son Lorenzo Dominic! I had my little man last night, healthy at 6lbs! HE\'S MY WORLD!\" she wrote on Twitter, then added a heart icon. Polizzi, 24, and fiance Jionni LaValle had their baby shortly before 3 a.m. Sunday at St. Barnabas Medical Center in Livingston, N.J. A Polizzi representative told MTV: \"The world just got another Guido! Lorenzo Dominic LaValle has entered the world weighing 6 pounds, 5 ounces. Nicole, Jionni and Enzo are doing great!\" \"Jersey Shore\" created a bit of controversy when it debuted in 2009 for the willingness of eight 20-somethings sharing a Jersey Shore summer house to call themselves \"guidos\" and \"guidettes.\" A \"guido\" is often viewed as derogatory for a working-class urban Italian-American man or sometimes for an Italian-American man who conducts himself in a thuggish, overtly macho manner. LaValle wrote on Twitter Monday he didn\'t know \"what I enjoy more, watching my fiance sleep or watching my son sleep,\" adding \"Both are amazing! #Lafamiglia\" Other Twitter messages from Polizzi, who didn\'t let giving birth keep her from the social network, include: -- \"Being a mom is an amazing feeling!!! I love my little man to death! Jionni is such a cute dad.\" -- \"Hardly any sleep but SO worth it!\" -- \"Im finally able to eat eggs again! While I was pregnant I couldn\'t even smell them! Now I\'m killing it with egg whites!!! #YUM\" Polizzi is one of the highest paid reality stars, earning $150,000 per episode as of Season Five, which ended March 15. MTV confirmed the series would return for a sixth season. She says she got the nickname \"Snooki\" in high school because she was the first of her friends to kiss a boy. Snooki was a male character in the 2001 MTV film \"Save the Last Dance.\"
