U.S. reality TV star Jenni Farley had double the reason to celebrate this Christmas - she is pregnant with her first child. The former Jersey Shore star, aka JWoww, announced on her blog on Wednesday (25Dec13) that she and her fiance Roger Matthews will welcome a baby together next summer (14). She wrote, "Merry Christmas from within! Roger and I couldn't have asked for a better Christmas gift this year...! "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!" Farley, 27, then shared a picture of their online Christmas card, which featured an ultrasound image of her unborn child, alongside the message: "Happy holidays from our growing family to yours." JWoww will be the third member of the Jersey Shore cast to become a parent - Nicole 'Snooki' Polizzi gave birth to baby Lorenzo last year (12), while DJ Pauly D learned he had fathered a little girl named Amabella earlier this year (13) after a fling with a Las Vegas waitress.
