The diminutive star is currently expecting her first child with fiance Jionni LaValle but her co-stars on the MTV show insist carrying a child won't stop her from having fun.
Deena Cortese exclusively told BANG Showbiz: ''Whenever we go through things we're in it together. She's really happy. We were all pretty surprised but happy though, she's our little meatball.
''We have no idea how it's all going to work with Snooki's baby but she hasn't had the baby yet so we've got a few months.
''She's been filming so I haven't spoken to her much, but she seems to be doing all right.
''We're so happy to be that we get to return for season six and I'm pretty sure everyone is on for the new series.''
Meanwhile, their co-star Vinny Guadagnino defended his season five threesome with a lesbian couple, saying he is sure his parents got up to some equally racy antics when they were his age.
He said: ''Obviously some things I don't talk about with certain members of my family like my mom but they understand these are my twenties, I'm living my twenties, this is what we do on the show, my life is documented. Some of the things I do probably aren't half as bad as what some of my family members did at my age. I'm a saint compared to some of them but they just can't look back on it on tape.''
'Jersey Shore' airs Tuesdays at 9pm on MTV.
