Wow, indeed!

Jenni “JWoww” Farley married longtime boyfriend Roger Mathews on Sunday, but the nuptials weren’t even the biggest news of the day -- the couple is expecting baby No. 2!

A source close to the couple confirms to ET that they announced their pregnancy to friends and family at their wedding at Addison Park in Keyport, New Jersey.

The newlyweds are already parents to 1-year-old daughter Meilani Alexandra Mathews, who was born July 13, 2014. Farley and Mathews did not announce if they know the gender of their new bundle of joy yet.

"It's true! We are expecting baby #2!" JWoww told ET on Monday morning. "Roger and I really wanted to make the announcement at our wedding surrounded by our family and friends! We are beyond and excited that Meilani will have a sister or brother next year!"

The ceremony was a truly Jersey Shore wedding -- JWoww’s former co-stars Nicole “Snooki” Polizzi, Sammi “Sweetheart” Giancola and Deena Nicole Cortese stood beside her as bridesmaids, and Vinny Guadagnino, Paul DelVecchio and Ronnie Ortiz-Magro were all in attendance.

Back in June, Farley gifted her pals with a “bridesmaids box,” and Polizzi couldn’t hold back her excitement for her BFF. "Congrats to my beautiful best friend on her upcoming wedding. Love you forever," the mom of two sweetly Instagrammed.

Earlier this month, Farley posted throwback photos on her website “to when it all started to feel so real.” She shared images of some of the dresses she tried on as inspiration for the gown she ultimately custom-created with designer Stephen Yearick, who she says “has brought my dream dress to life.”

Even cuter? Meilani wore a tiny version of the gown during the Oct. 18 ceremony. “I can’t wait for her to wear it!” Farley wrote two weeks ago. “I already know she is going to steal the show!!”

At least Farley was comfortable sharing the wedding spotlight with her mini me! We hope that through out the festivities, Meilani sounded a little bit like this:

As for Farley’s husband, last week Matthews shared on her blog that he “could not be more excited to celebrate our love and our family with all our nearest and dearest.”

Farley, 29, met Matthews while she was filming season three of the Jersey Shore. Matthews, 38, proposed to the MTV reality star after a skydiving trip in September 2013, popping the question with a 5-carat ring surrounded by 2.5 carats of pink and white diamonds. The two were also on the Shore spin-off Snooki and JWoww and made an appearance on Marriage Boot Camp: Reality Stars.
