The happy couple, played by Kym Marsh and Keith Duffy, will soon be back on the cobbles with the news that they are tying the knot, according to the Sunday Mirror.
"Michelle and Ciaran are two of our most popular characters," a show source told the newspaper. "They will return from their cruise and tell the street they are planning a huge wedding.
"But this is Corrie and the course of true love never runs smooth, so anything could happen before they say 'I do'."
Marsh has been on maternity leave from Coronation Street in recent months and gave birth to a baby girl named Polly in March. Meanwhile, Duffy took time out from the soap to go on tour with Boyzone.
He said in a TV interview: "This return to Corrie is not going to be as long as I would have hoped, because I'm kind of needed in Dublin this year.
"[My son] Jay has a big exam year, and my little girl Mia, who has autism, it's her last year in [primary] school and the transition to secondary school is going to be a lot of work for everybody. I'm kind of needed there to try and help make that happen."
Marsh also recently speculated that there could be heartbreak ahead for the pair.
"I'm not sure what [Keith's decision] means for Michelle and Ciaran's relationship because I haven't seen any storylines, but if they do break up it will be interesting to see if he breaks her heart or she breaks his," she said earlier this month.
Marsh and Duffy are expected to film their Coronation Street comeback scenes within the next few weeks.
