Shortly after her gorgeous nuptials in Italy, Leona expressed her desire to have children and revealed she would like to adopt because of her mother's experience growing up in a children's home.
"I do want children, but Dennis and I have also talked about adopting," she told Stella magazine. "My mum grew up in a children's home. No one adopted her as a child, and I would very much like to adopt. But I'm still figuring things out. If it was up to my husband, we would have had kids yesterday."
The 37-year-old singer, who won the third series of X Factor in 2006, married German-born creative director Dennis after ten years of dating.
Speaking exclusively to HELLO!, she said: "It was just the most beautiful day, full of love. It was so special to be able to bring together everyone we love. There were a lot of tears."
