It's double joy for the newlyweds, who announced their baby news to family and friends at their wedding celebrations on Sunday (18 October), just hours after exchanging vows.
The couple married in a romantic ceremony in New Jersey on Sunday, but it only emerged some time later that it was in fact an extra special celebration for the pair.
JWoww and Roger, who are parents to one-year-old daughter Meilani, shocked guests at their wedding after bringing out a sign which featured a photo of Meilani and the words, "I'm going to be a BIG SISTER!! May 2016".
Confirming reports, JWoww took to her website and explained: "IT'S TRUE, WE ARE EXPECTING BABY NUMBER TWO!! (Hey, that rhymes, lol.) So tired from all the wedding fun but wanted to share with you guys the news so you get it from me first.
"I will update you more ASAP. All I know THIS was the hardest secret to ever keep!! We are so excited to share it with you guys, though. And keeping it a secret was worth it for the response last night from all of our family and friends. The best!!! So YES, Meilani is going to be a big sister and we are due in May 2016!"
Before signing off, JWoww said: "HAPPIEST DAY OF MY LIFE LAST NIGHT!! (Well, tied with the day Meilani was born). Married to the man of my dreams and the best daddy to my babies!! Can't wait for you all to see the wedding pictures!"
