"I have spoken to Kelly on the phone and apologised," the Mirror quoted Cowell, as saying. "She was very pragmatic and very professional about it, although obviously a bit sad about no longer being a judge. I am sure she had shed a couple of tears but she"s a tough little cookie," he added.
Cowell also revealed that he offered the 29-year-old actress a job on his spin-off show to make up for it. "I've offered Kelly a part on my ITV2 show. I actually liked her she was good, she was fine," Cowell said.
"The problem was not her. Britain's Got Talent just doesn't work with four people. She is a warm person, who looks great and is very enthusiastic and that is why I spoke to her about the ITV2 show. I hope she'll accept," he added.
