Jenni "JWoww" Farley and Roger Mathews

Jenni "JWoww" Farley married her longtime boyfriend, Roger Mathews, over the weekend, and that wasn't the only thing the couple had to celebrate.

ET reports that Farley and Mathews are also expecting Baby No. 2. The new addition will join big sister Meilani, who was born last July.

Farley and Mathews, who have been engaged since September 2012, tied the knot on Sunday. InTouch was the first to report the news.

In a blog post on Farley's website Friday, Mathews wrote that his wife-to-be was "very calm" in the days leading up to the wedding. And, he added: "Meilani has been in a great mood all week ... Think she knows her Mommy and Daddy are about to have a very special day."

Meilani was a flower girl at the ceremony, and Farley's former Jersey Shore co-stars Nicole "Snooki" Polizzi, Deena Cortese and Sammi "Sweetheart" Giancola were bridesmaids, according to Us Weekly.
