Simon Cowell arrived at LAX last night and was greeted by hoards of fans and photographers, and the music mogul was asked how fatherhood was treating him since becoming a dad to newborn son Eric.

The X-Factor head hauncho was specifically asked if he changes dirty diapers, but in typical jokester fashion, he gave a witty response rather than a straightforward answer.

"Not at the moment," he quipped.

That sounds like a no to us!
