JWoww, aka Jenni Farley, late of MTV's 'Jersey Shore,' is pregnant!

The former reality star is expecting her first child and took to her website on Christmas Day to announce the news, posting a photo of her sonogram in the form of a Christmas card. How cute.

The baby daddy is her fiance Roger Mathews.

J Woww, who used to cause 'trouble' down the shore with Snooki, herself a new mother to son Lorenzo, 1, posted the following note, sharing her good news with all of 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!
Jenni, Roger and Baby Mathews

PopCrush sends our congrats out to the happy family.

The 'Jersey Shore' cast members are all grown up and starting families. Good for the guidos and guidettes, as they refer to themselves.

Snooki shared her son Lorenzo's photo on Santa's lap right before Christmas. You can see the poor kid crying his face off here.

Snooki also took a minute to offer JWoww some baby advice, which the expectant mom shared. See it below!
