After becoming a dad for the first time in February, music mogul Simon Cowell now wants another child with girlfriend Lauren Silverman.

The 54-year-old welcomed son Eric in February and now he wants to extend his family, reports dailymail.co.uk.

"Of course I'd like another child. You have one, and I'd always have another," he said.

"I've thought about having one in between the series of 'X Factor'," he added.

Although he's a devoted dad, Cowell says he has still to change his son's nappy.
