Speaking on RTE’s Morning Ireland programme, Sean O’Dowd told broadcaster Rachael English that the family are looking forward to welcoming their tenth grandchild.
He said proudly: “I was tapping it’s outer skin – in other words it’s mammy’s tummy - last night and Dawn is in the very best of form.
“It will be the first child for Chris, and the first child for Dawn. It will be our tenth grandchild. Please God, towards** the end of January** I will be a grandfather for the tenth time."
Chris O'Dowd, 35, and Dawn O'Porter, 35, have previously lived in Dublin and London but are now based in Tinseltown and are planning on having their first child Stateside.
