The music video shows the singer sitting at the kitchen table, with his wife Giovanna, slicing through pumpkins to produce the message:"We're having a baby."
It ends with a scan of the baby - the couple's first - with a caption which reads "Arriving 2014".
The video is captioned: "Sometimes the best way to say something is with a pumpkin...and a song."
After the video was posted online, Fletcher took to Twitter to alert his fans, writing: "Me and Mrs Fletcher have some rather exciting news to share with you."
He added: "Thank you very much for all the lovely messages. We couldn't hide it any longer...literally."
It is not the first time Fletcher has chosen to share personal moments with his fans with an online video.
After charming guests at his wedding by delivering his speech to the accompaniment of the tunes from his songs, the singer shared the video on YouTube, where it has been seen more than 11 million times.
