Emma gave birth to a son on Friday, and the couple have joined the bizarre baby names club, naming their new arrival, Ace Billy.
The couple already have a two-year-old daughter, called a more traditional, Isabelle.
Matt tweeted the news earlier, with a nod to the grief the couple are probably going to get over their name choice:
"I have a son and his name is Ace! Went for Billy [as his middle name] so if he wants to be like a f**king banker or something he can use that instead!"
Congratulations Matt and Emma!
What you do make of the name, Ace?
