London, July 1 Simon Cowell's ex-girlfriend Terri Seymour thinks that it's time for the music mogul to retire from one of his hit shows and enjoy his golden years.

Seymour and the X Factor judge have remained close friends despite the music mogul's gruelling schedule.

Seymour, who parted ways with the Cowell this year, thinks that her ex is working too hard and needs to slow down.

"I think all his work is tiring Simon out and he's finding it hard," the Daily Star quoted Seymour as saying.

"He'd hate me saying this but he's not as young as he used to be. He's got such a tough schedule and at some point one of the shows will have to give. We'll just have to wait and see which one," she added. (ANI)
