A "Jersey Shore" cast member is going to be a new mother! Jennifer "JWoww" Farley is expecting her first child with fiancé Roger Mathews.

JWoww, 27, and Mathews, 37, announced the big news on the "Jersey Shore" star's official blog with a photo of the sonogram and a special message to her fans:

Merry Christmas from within! Roger and I couldn't have asked for a better Christmas gift this year! 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. 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!

Happy holidays from our growing family to yours!

Love,

Jenni, Roger and Baby Mathews

The couple has not confirmed if the baby is a boy or a girl, but it's too soon to tell. JWoww listed her due date as July 2014, meaning she is about two months along in her pregnancy.

Still, he or she most likely have a play date set up with Nicole "Snooki" Polizzi and her 1-year-old son Lorenzo. Fellow cast member Pauly D is also a proud father to a baby girl named Amabella, but he might no be able to schedule any play dates for a while.

Pauly D is currently tied up in a custody battle for Amabella, in which he is seeking full custody for his little girl. The DJ is in high spirits and told TMZ he is making the best out of the situation, including giving his daughter the best Christmas presents ever.
