'Jersey Shore' Star Jenni 'JWoww' Farley Welcomes Second Child

— -- Former "Jersey Shore" star Jenni "JWoww" Farley got a very special gift ahead of Mother's Day. She welcomed her second child Thursday night.

Her husband, Roger Mathews, announced the news Friday by sharing a photo of the delivery on Instagram.

"Yesterday at 6:03 pm (with the help of my assistant Dr. Rezai and my wonderful staff) I delivered our 7 lb 2 ounce son Greyson Valor Mathews into the world," he wrote as a caption.

Baby Grayson will join the couple's 21-month-old daughter, Meilani.

Mathews, who also starred on "Jersey Shore" and its spin-off "Snooki & Jwoww," added: "What an amazing experience to literally witness the miracle of life from the very onset. He's our little man, our perfect bundle of joy, the baby brother to an anxious little girl ready to met her Bubba. What a ride this this thing called life is ladies and gentlemen."

Farley, 30, and Mathews announced the pregnancy during their wedding reception last October.
