Cowell let the news slip during a recent interview with U.S news show Access Hollywood when reporter Shaun Robinson asked the dad-to-be if he would be strapping a baby seat into his Bugati sports car ahead of his first child's arrival.
He said: "Yes, of course he's got to learn how to drive very quickly."
Robinson didn't pick up on what The X Factor boss said right away and asked the follow-up question: "Have you found out the sex of the baby yet?" prompting an embarrassed Cowell to respond, "I think I just gave it away, Shaun."
The interviewer replied: "You certainly did. Oh my gosh!"
Cowell then added: "Everybody knows anyway. It's a boy... The first time I saw it (on an ultrasound)... I called him Tad, because he looked like a tadpole. I still wanna call him Tad."
Cowell's girlfriend Lauren Silverman confirmed reports she's expecting a baby with him this summer.
