If new mom Nicole "Snooki" Polizzi wants a night off, she's in luck! Two weeks after giving birth son Lorenzo, the "Jersey Shore" star, 24, tweeted that "Rihanna's 'We Found Love' will never get old to me. It's my song for life."

Since becoming a first-time mom August 25, Polizzi -- engaged to love of two years Jionni LaValle -- has been relaxing at home, watching shows like "The X Factor" and tending to her newborn. "Laying in bed with Lorenzo in my arms (is the) best feeling in the world," she tweeted Sept. 15. She also said that "the breast pump bra is a miracle. Thank you for making it so much easier."

When Polizzi first shared the news of her pregnancy in an Us Weekly cover story in March, the reformed party girl said she and LaValle won't be tying the knot until 2013.

"We will focus on the baby first. I want to have the baby, lose weight and have the baby in the wedding," Polizzi told Us. "I want it in my church, with a reception in Jersey somewhere. I want bombs going off at the reception -- fireworks. And I want a princess-type gown with a huge train."
