Marriage and a baby!

Newlyweds Jenni "JWoww" Farley and Roger Mathews announced that they're expecting their second child together at their wedding reception on Sunday.

"Baby No. 2 is official!! We are expecting and couldn't be more excited," Farley and Mathews told Us Weekly. "A wedding that was beyond a dream come true and baby No. 2 on the way, we couldn't ask for more. We are on cloud nine!"

The expecting reality star told E! News exclusively, "This was one of the hardest secrets to keep but it was one of the most memorable parts of our wedding! The reaction from everyone was priceless. Roger and I only told our publicist and our nanny that we were expecting, so to watch everyone's face when Roger announced it was priceless."

The two also revealed they were expecting by bringing out a sign with a picture of their 15-month-old daughter Meilani, with the words, "I'm going to be a BIG SISTER!! May 2016."

No additional details regarding the unborn baby, including the sex and possible due date, has been revealed. JWoww and Matthews tied the knot in a romantic ceremony in front of friends and family at Addison Park in Keyport, N.J.

As previously reported by HNGN, JWoww's "Jersey Shore" cast mates Nicole "Snooki" Polizzi, Deena Cortese and Sammi "Sweetheart" Giancola served as bridesmaids. Former co-stars Ronnie Ortiz-Magro, Paul "DJ Pauly D" DelVecchio, and Vinny Guadagnino were also in attendance. The couple's daughter severed as the flower girl.

"Roger is my perfect man in every way and he is the best daddy to Meilani that I could ever ask for," she wrote on her website this weekend prior to saying "I Do." "He accepts me in every way and I am more in love with him than ever!"

Farley and Mathews met while she was filming "Jersey Shore" in 2010.  He proposed to Farley in Sept. 2012 with a 5-carat pink and white diamond engagement ring during a skydiving session.
