The British singer, who welcomed baby Zachary on Christmas day, said that caring for their son has made their bond stronger than ever.
The 63-year-old singer told Hollyscoop, 'It's made me very relaxed, it's definitely brought David and I closer together. We were pretty close together anyway - we have been together 17 years - but it's definitely brought us closer together.
'It seems to be that everything in my life is so wonderful. I have a wonderful partner, an incredible career, fantastic friends, I have my health, and I have a child. I'm the most blessed person in the world I think, I pinch myself sometimes and think, 'God,' you know?'
