The first trailer for Snooki and JWoww's "Jersey Shore" spin-off is out, and naturally, it's all about Snooki's engagement and pregnancy.

It even features the moment when Snooki dropped the big news on JWoww (or at least a dramatically staged re-creation of that moment).

Our favorite line is when Snooki says,

"Honestly, I really didn't know that I could make a baby . . . so the fact that I can reproduce is very scary."

We couldn't agree more Snooki.

Snooki also told reporters yesterday that she has calmed down since becoming pregnant.  She said,

"I guess [pregnancy] just made me more mature.  It's different because now I'm not drinking. I'm usually partying and going to clubs, but pregnancy made me grow up a lot."

Maybe Snooki and her baby can grow up together.
