The couple, who play Debbie Dingle and David Metcalfe in the popular soap announced their news on Twitter in the best way.
The 27-year-old actress and her fiancé already have a five-year-old son, Buster who was a central part of their baby news announcement.
Webb uploaded a black and white photo with Buster behind a sign that said "Only child expiring Dec 2015".
The couple are also featured in the photo with Wolfenden holding a sign with an arrow pointing at Webb's stomach and the caption: "Baby# 2".
Webb wrote: "Here we go again..." on the tweet to her 351,000 followers.
It seems her fans were very excited about the news. One woman wrote: "WHAT OMG CONGRATULATIONS OMG SO HAPPY FOR YOU."
Wolfenden tweeted the same photo from his personal account followed by a thank you message for all the messages they've received.
He then tweeted some not-so-exciting news about the laminate flooring in his caravan, before asking his fans: "What are the congratulations for, the baby or the flooring?"
The couple have had a slightly rocky road, as they split earlier in the year.
Wolfenden told The Mirror back in April: “It was never a permanent split, we just needed some time apart. Sometimes life just gets on top of you.
"We had a terrible two-year-old at the time and needed time to look at what we had but it was the best thing we could have done."
He added that although they are still discussing a wedding, it's not something they are desperate to do tomorrow - but they would like to get married on a beach abroad.
Well, now a baby is on the way they have a whole lot more planning to do aside from the wedding. Congrats to the couple!
