CBS announced the show, which has the working title Bake Off, earlier this month.

The Sun quotes Berry as saying: "I have no idea if I will be asked. I've not thought about it and I'm not going to think about it, as it would mean being away a lot."
However, Berry's fellow judge Paul Hollywood has apparently said that he would be interested in a role on the show, potentially as its host.
An insider recently claimed that executives are "desperate" for Berry and Hollywood to be involved in CBS's Bake Off, as they believe that the pair's "lightness of touch" will be popular with viewers in the United States.
Richard McKerrow, who launched the series in the UK as executive producer, will oversee Bake Off for Love Productions USA.
International versions of the show have already launched in countries such as Belgium, Denmark, Sweden and Poland. The format will also premiere in Australia, Ireland and France during 2013.
