(Yahoo!) - It looks like Snooki's son Lorenzo is about to have a new friend. That's because her best friend Jenni "JWoww" Farley is pregnant!

JWoww, 27, announced the happy news that she and fiancé Roger Matthews, 37, are expecting on her personal website on Christmas Day, posting a message to her fans along with a greeting card that contained her ultrasound. She then tweeted out a link to the exciting news. 

"Merry Christmas from within!" JWoww's note began. "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!"

Snooki was quick to tweet her reaction:

JWoww and Roger have been engaged since September 2012. Following the end of their hit MTV show, "Jersey Shore," JWoww has starred in the successful spin-off show "JWoww and Snooki," which is currently airing its third season.

Congratulations to the happy couple!
