Dad-of-five Ronan has three children from his first marriage to ex-wife Yvonne: Jack, Missy, 21, and Ali, 16.
He has two young children with second wife Storm: Cooper, four, and Coco, one.
The blended family are a close unit as can be seen in a smiley picture of them all at a black tie event in memory of Ronan’s mum Marie, who died from cancer in 1998 aged just 51.
Just last month Ronan paid tribute to eldest daughter Missy as she reached the life milestone of 21.
“Happy Birthday to my Missy Moo,” he wrote. “This picture says it all. We laugh Moo all the time. My family are my world my kids are me.
“I am so bloody proud of you Sweetheart. You walk into a room and the place lights up. You are my sunshine.”
He continued: “I cannot believe you are 21 the years have flown. But you have blossomed into everything I could ever want in a daughter and more. Storm and I love you with all our hearts.
“We know you are ready for the world now moo I just don’t think the world is ready for Missy. Love ya sweetheart.”
