The Jersey Shore star looked happy and healthy as she filmed an appearance on Access Hollywood Live in chilly Manhattan on Monday (13 January).
Jwoww announced on Christmas Day that she and fiancé Roger Mathews are expecting their first child.
"We are so excited to share this new chapter of our lives with you as we become parents and create more memories with a new addition to our family!" she wrote. "We are extremely happy and cannot wait for our bundle of joy to arrive! Happy holidays from our growing family to yours!"
So far, the couple have not revealed any other details, such as a due date or whether they know the sex of their baby.
Jwoww has, however, promised to keep fans updated throughout her pregnancy by posting regular updates on her official website.
Last week's update described how she discovered she was pregnant just before flying to Nashville to attend a tanning convention- she owns a tanning range – but her excitement was marred with fear after she began bleeding at the airport.
"So many thoughts were running through my head. I felt a loss like no other when I thought that I was no longer pregnant. I whispered it to Roger and for that whole ride we just stared straight ahead and didn't say a word. I went to bed that night in Nashville praying it was just a thing that happens.
"The following day I told my manager to buy a "stupid proof test" which literally says "pregnant" or "not pregnant." It said pregnant and she cried and I cried and Roger looked like he was going to pass out! Hahaha. That day in Nashville I was on cloud nine."
Jwoww and Snooki now appear on their own spinoff reality show.
