The fun 85 second clip sees the couple belting out such classic lines as: "Do we really want a baby? We forget to feed our dog.
"But maybe it's overdue? We started hanging our pets' pictures on the wall. We're gonna have a baby."
The couple cannot hide the winces that come with hitting those high notes (you might want to turn your sound down!), but the pair dissolve into giggles at the end, with Ed declaring, with a note of bemused glee that any first time parent-to-be will recognise: "Oh my god. I'm totally unprepared for this, guys!"
Congratulations Mandy and Ed!
