Nicole Snooki Polizzi revealed to In Touch Weekly magazine that she's expecting a baby boy with fiance Jionni LaValle in September.

The Jersey Shore star tells the magazine that she and Jionni have it narrowed down to two names - Lorenzo or Jionni Jr. - for the tot, even though she was hoping for a girl.

"Everyone said I was going to have a boy, and they were right!" she says.

"I thought it was going to be a girl," she adds. "I was hoping it would be, because all girls want girls."

"It's still my baby, no matter what. I'm excited either way!"

Snooki proudly showed off her baby bump on the cover of the new issue of the magazine (on newsstands now); but she reveals that despite her anticipation she doesn't feel that great physically - especially when it comes to smushing!

"Our sex life is hardly there! I just feel too icky and gross," she overshares. "I'm so not in the mood to do stuff."

Snooki's also planning on curbing her partying ways.

"I'm not going to party hard anymore," she says, "even after the baby is born. Being a mom changes you."
