Jersey shore alum, Jenni "JWoww" Farley, is pregnant with her first child!

The MTV reality star tweeted on Wednesday, "Santa brought Roger and I the best gift of all..." and a link to a photo where she made the official announcement about her pregnancy. The picture was of a Christmas card Farley, 27, and fiancé Roger Mathews shared that showed off a sonogram image.

"We couldn't' have wished for a better gift this Christmas! Happy Holidays from our growing family to yours! Love, Jenni, Roger and arriving July, 2014 Baby Mathews." the card read. 

Now in her second trimester, Farley also broke the news on her website.

"We wanted to share this exciting news with you all first because you have been a part of our lives these past few years and seen the love between Roger and me develop and blossom," she told fans. "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!"

"Thank you for all your love and support and for being there for us throughout the years! We are extremely happy and cannot wait for our bundle of joy to arrive!" she added.

The couple got engaged in September 2012. The baby-to-be joins fellow Jersey Shore alum Snooki's son Lorenzo, and DJ Pauly D's daughter Amabella, born earlier this year. The sex of the baby has not been revealed, but according to Snooki and JWOWW's plan, it will be a boy.

"She has to have a girl sometime and I have to have a boy, and they either have to get married or have kids together," Farley explained to MTV.com back in June of 2012, when Nicole was pregnant with Lorenzo.
