Speaking to the Express, he said, “Louise and I sort of share the kids, they spend time with me and they spend time with her, that’s the way we want to do it.

“The boys will probably go to Louise’s families on Christmas Day and I’ll have them Christmas Eve and Christmas morning.”

Meanwhile, Louise has admitted that her wish for Christmas is to enter the New Year feeling happy in her life, telling Stella magazine, “I’m past presents and all I want is to be happy.

“I know that sounds really clichéd but I just want to go into the New Year feeling content. That would be the best present.”
