Simon Cowell is open to the idea of adding a second child to his brood because fatherhood is "fun".

The 55-year-old music mogul welcomed his first son, Eric, with girlfriend Lauren Silverman in February, 2014 and he admits having another baby could be on the cards.

Cowell tells Britain's Daily Star newspaper, "I wouldn't rule anything out right now. It's been fun and much easier than I thought. He's adorable, so maybe I just won't make plans and see what happens... The last year has been kind of unexpected but good, I'm enjoying it."
