The 80-year-old TV star launched 'The Great Holiday Baking Show' on ABC in America last month but it has already lost 700,000 viewers and is now believed to be in jeopardy.

A source told The Sun: "This show is sinking in front of our eyes, and that is not what ABC expected to happen. To lose one in six viewers in one week is a disaster.

"Had the audience stuck at the four million mark, that wouldn't have been so terrible. But the figures have just kept falling.

"You can't say ABC really committed, with only four episodes made. Given these results, they aren't likely to go for a summer series. It's a shame, as everything Mary touches in the UK turns to gold."

In 2013, Mary's co-star Paul Hollywood appeared in 'The American Baking Competition'.

However, that also failed to impress viewers and was axed after seven episodes.

A source said at the time: "It's over. It's been cancelled. We've all been waiting for CBS to tell us if they were going to pick us up for a second series and this week the call came in saying it's not being renewed and we should take alternative employment offers.

"Critics hated it and the ratings were abysmal. None of us are particularly surprised, to be honest."
