Los Angeles, Jan 31 (IANS): Singer John Legend says he cannot wait to have children with his wife Chrissy Teigen and insists it is "only a matter of time" until she becomes pregnant.

"We want to have kids, so it's just a matter of time. Whenever it happens, we'll be excited," the "All of me" hitmaker, who married the model in Italy last year, told Us Weekly magazine.

Legend says he and the brunette beauty "try to be together physically whenever we can", but are also very focused on their own careers.

"We want each other to be happy, and part of that is being fulfilled in our work and loving what we do. We're there for each other," he added.

The crooner recently admitted it took him a few years to realise Teigen, 29, was the one.

Asked if he fell in love with her the moment they met, he said: "Not right away. I'm more cautious than that.

"I wasn't like, 'This is the woman I'm going to marry,' from day one. For me, I'm the kind of person who needs to grow into that feeling. It was probably a couple of years in, when I could already see us being together forever."
