X Factor finalist Mary Byrne among the contestants on Celebrity Operation Transformation

X Factor finalist Mary Byrne has been included as one of the contestants on this year’s Celebrity Operation Transformation.

“I had to ring my manager back to find out was she messing — so I was thrilled, really thrilled [to be asked],” said Byrne, 58.

“Two years ago, I did a juicing diet and I lost near enough two stone and I’ve kept that off for two years only due to my daughter, but I haven’t lost anything since that.”
