"Welcome to the world," the famous children's entertainers posted.

The couple became engaged in April, with Stephenson writing on Instagram that she "walked into the most beautiful surprise".

"A room filled with the most incredible flowers and Lachy singing at his piano and then asking me to marry him. It was such a surprise and so special. Our faces say it all.

"It was something very meaningful for us to both have the opportunity to propose to one another, each in our own way," she wrote.

At the end of our summer holidays, I walked into the most beautiful surprise - a room filled with the most incredible flowers and Lachy singing at his piano and then asking me to marry him. It was such a surprise and so special. Our faces say it all. It was something very meaningful for us to both have the opportunity to propose to one another, each in our own way. Last week, with the most beautiful (and excited!) little boy by my side in a special bow tie, it was our time to ask Lachy our special question - and it was so, so wonderful 💕💕
