Laboring SNOOKI wanted a BIG stiff one in the worst way imaginable! IN the hours leading up to the arrival of Snooki’s first baby, the party-hearty “Jersey Shore” star was focusing on one thing – her next DRINK!

As TV’s favorite bad girl prepared for motherhood, her thoughts were far from baby bottles, baby food and diapers, says a close source.

“Snooki said all she was looking forward to was her first cocktail!

“She’d already decided on naming the little guy Lorenzo. And she felt she was the model of prim-and-proper prenatal behavior, so Snooki was more than ready to toast her newborn.”

Lorenzo at 6 pounds, 5 ounces, arrived at 3 a.m. on Aug. 26 and Snooki later boasted: “The world just got another Guido.”

Luckily for the baby, the bimbette, 24,  and her baby daddy Jionni LaValle found the hospital. They had bungled their practice runs to Saint Barnabas Medical Center, in Livingston, N.J., revealed the source.

“Snooki and Jionni did about 20 dry runs because they wanted to be prepared in every way – but they kept getting lost.

“Their GPS nearly melted!

“All through her pregnancy Snooki was determined to be a great mom and didn’t touch a drop of booze. But she said her dream about having her first ‘cold cocktail’ was the incentive she needed to make a safe delivery for her little one.”

Her chugging  drink of choice is the “Snooki Snack,” which a Jersey gin mill named after her. It’s coconut rum, creme de bananes, melon liqueur, pineapple juice and whipped cream.

New mom Snooki, real name Nicole Elizabeth Polizzi, is now working on a second major event – her wedding to Jionni.

“They became so busy preparing for the birth that their wedding plans went on the back burner, but Snooki knows exactly what she wants,” said the close source.

“She’ll have the fairytale white dress…and her bridesmaids will be in leopard print.

“And you can bet there’ll be plenty of ‘Snooki Snacks’ to celebrate!”
