Glamorous mum Yvonne Keating is "looking forward" to spending some time with her ex over the holiday break.
And she seemed completely relaxed when asked about the possibility that his new girlfriend Storm might join them on Christmas Day.
"We're all looking forward to being together on Christmas," she said.
"Ronan's been busy so it'll be great having him home for Christmas. I have no idea if Storm will be there."
Ronan introduced his children to his TV producer girlfriend Storm Uechtritz when they flew over to Australia in October.
Yvonne had to cut her trip to the theatre short last night after her seven-year-old daughter Ali got spooked during the opening number.
"Night out with the kids at Oliver was cut short when little Ali got a fright in the opening scene. No talking her into going back in," Yvonne (37) tweeted.
"Back home putting the kettle on. The few minutes I saw looked amazing."
Yvonne attended the premiere at the Bord Gais Theatre with children Jack (13), Missy (11) and Ali.
The blonde beauty said she was looking forward to a traditional family Christmas with the kids and Ronan (35).
Yvonne, Ronan and the children will be heading down to The K Club and the former model said couldn't wait to put her feet up and enjoy a drink or two.
"We go to the K Club for Christmas," she said. "It's a family tradition. I cooked the big dinner until a few years ago and then I stopped. I haven't looked back since. It's lovely to put the feet up on Christmas Day and be handed a glass of champagne."
Yvonne said a large group will be helping the family celebrate in style.
"We will have 20 guests in a private room with a big open fire. It's sure to be lively!" she said.
Yvonne didn't reveal whether her current partner, cameraman John Conroy, would be joining the party on Christmas Day.
And she added that she had not made plans for New Year's Eve. "I have no plans for the New Year. I'm taking it as it comes. No plans yet," she said.
