The Big Brother's Bit On The Side host, who confirmed her pregnancy in July, gave birth to a baby boy on Friday and the couple have named the child Ace Billy Willis.
"I have a son and his name is Ace!" Matt wrote on Twitter. "Went for Billy [as his middle name] so if he want to be like a f**king banker or something he can use that instead! (sic)"
Emma said that she was "knackered", adding: "I freakin love that name too!"
The pair, who married in 2008, already have a 2-year-old daughter together named Isabelle.
Emma was recently unveiled as the new face of Regis hair salons, saying she was "so excited" about her new job.
