WATCH Snooki is Having a Girl

Nicole "Snooki" Polizzi said her second pregnancy is nothing like her first.

Not only is she expecting a girl this time around, but she also feels much better.

"It's most definitely different from the last because I'm very active," she told ABC News. "Working out every day and eating healthy is making my pregnancy so much more comfortable and easier. Wohooooo to a fit pregnancy!"

Polizzi, 26, announced last month that she and her fiancé, Jionni LaValle, 27, were expecting their second child. Though they initially hoped for another son, they're excited that Lorenzo, who turns 2 in August, will have a sister to play with.

"Lorenzo is already so excited," Polizzi said. "He's going to be such a protective brother -- I already see it!"

She's also happy that she'll have a little girl at the same time as her best friend and "Snooki & JWoww" co-star, Jenni Farley.

"We are just like every other set of best friends: excited to have our girls be best friends and grow up together," she said.
