Simon Cowell mentioned on the X Factor show on Saturday that there was already a huge buzz in the states about X Factor contestant, Leona Lewis. But The Sun has revealed that the American offers have already started for Leona.

It is rumoured that Ellen DeGeneres has already invited Leona to appear on her chat show.

An insider said: “It’s a massive boost for Leona because Ellen’s show is huge in America and you have to be pretty special to get on.

“They have been checking her out each week on the show because there’s been a real buzz around her out there. They made contact and invited her to come and be a guest.�
