The 31-year-old star, who presented this year’s US version of I’m A Celebrity… Get Me Out Of Here!, said that she was in America when a group of men made the mistake.

She said: “These guys in a steak joint in Texas asked me to sign something to put up on the wall.

“I wondered why they’d been fussing over me and then realised who they thought I was. All because I put on 10lbs!”
