Former "Jersey Shore" star Jenni "JWoww" Farley has welcomed her second child, a boy.

In an Instagram post, JWoww says Greyson Valor Mathews was born Thursday night, weighing in at just over 7 pounds.

She says the "most beautiful part" was that husband Roger Mathews was able to help with the delivery.

JWoww's publicist confirmed the announcement.

This is the second child for JWoww and Mathews, who was a regular on "Jersey Shore" and its spinoff "Snooki & JWoww."

The couple also has a daughter named Meilani, who was born in July 2014.
