Brace yourselves, there's about to be another one.

So which Jersey Shore star has announced a pregnancy?

Jenni 'JWoww' Farley announced on her website that she and fiance Roger Mathews are expecting their first child in July 2014.

JWoww is the third cast member to become a parent. Nicole 'Snooki' Polizzi gave birth to son Lorenzo in August 2012, and Paul 'Pauly D' DelVecchio welcomed a daughter earlier this year.

The announcement included a sonogram picture and thanks 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

Congrats to JWoww and Co.!

As much as the cast of 'Jersey Shore' annoys me, you can't be mad about a pregnancy. (Until of course it turns 21 and comes to our area to fist pump and drive too slow in the left lane.)
