Proud parents John Thomson and his wife Samantha have showed off their second daughter Sophia Melody - who was conceived naturally following three failed IVF attempts.
Thomson, who was recently on screens as Jesse Chadwick in Coronation Street, vowed he would install "machine gun turrets" on his front gate when his daughter reached her teens to keep boys away.
Thomson told Hello! magazine that when his wife broke the news she was expecting: "I was just bowled over, in total shock. Here was Sam pregnant and with a baby naturally conceived."
But asked what he would do when his daughter reaches her teens and boys start coming to call he replied: "I'll fit machine gun turrets on the front gate."
Their baby was delivered by Caesarean in March, weighing in at 7lb 7oz. The couple agreed that the Cold Feet actor should be the one to cut the cord and to reveal the baby's sex.
Sophia was lifted into her mother's arms to the strains of Elvis Presley singing That's All Right (Mama).
"I said it was a girl," said Thomson, "and Sam burst into tears".
Thomson, who has battled drink problems in the past, told Hello! he has not touched a drop in three and a half years.
He said: "I can honestly say I don't miss it. Everyone knows I'm reliable again. When I was on the booze, everyone knew I was unreliable. I'm never going back to those days. I've got too much to lose."
The couple also have a seven-year-old daughter named Olivia. Samantha, 40, added: "All I wanted was another baby. If you're lucky enough to have more than one, it feels like a proper family."
