The 'Gotta Be You' singers have been ringing the music mogul in a variety of accents.
One Direction have been perfecting their best accents to make prank calls to Simon Cowell.
The former X Factor contestants got hold of Simon's number and have revealed that they have been teasing him down the phone.
Louis said: "We did one in a Brummie accent. We said, 'Seymun, y'alreet?"
"We said something about his trousers being so high," added Zayn.
The 'What Makes You Beautiful' singers were mentored by Simon during last year's series of The X Factor and have just finished filming in London for their new video 'One Thing'.
Meanwhile, One Direction are set to perform at Capital FM's Jingle Bell Ball this Sunday (4th December).
