One source said: "Chris and Katherine met up with Arnold and his girlfriend Heather for Sunday breakfast at the FIG restaurant. Arnold seemed happy that Chris and Katherine joined him."

Whilst another insider added to People magazine: "A lot of laughter and storytelling. Arnold seemed very pleased to spend time with Chris. It was obvious that they got along and enjoyed getting to know each other. They had eggs, breakfast meats and fruit. Chris settled the check."

And things are going from strength to strength between the couple.

She has always been good with children, but she really shines and has stepped in to this role perfectly. She knows her place with him and is there to have fun and support him.
