Cowell is said to be producing the show in collaboration with Topshop billionaire Sir Philip Green, one of Kate’s close friends.
According to reports, the show will be a cross between Simon’s flagship X Factor and Britain’s Got Talent, giving an unsigned group the chance to become rock stars.
It is expected to launch in the US with a British spin-off following later.
The show will mark Kate’s first mainstream TV role, and a remarkable turn around for the model whose career was almost destroyed when she was caught snorting cocaine in 2005.
“Kate is absolutely cock-a-hoop about her move into TV,” the Mirror quoted a source close to Kate as saying.
