The author and TV presenter was seen touching her nose and wiggling her fingers during the first episode of the series, when contestants were told who would be competing in the first trials.
Sure enough, Fletcher was one of the chosen ones, and the CBeebies presenter and mother of three endured her first trial, which involved terrifying heights.
Fletcher’s husband, Tom Fletcher, a lead vocalist and rhythm guitarist from the band McFly, has revealed exactly what her hand gestures signified.
Speaking to Phillip Schofield and Holly Willoughby on the ITV chat show This Morning, the musician was asked whether one of Fletcher’s hand movements was “for the boys”.
“Yeah that was a little signal,” he responded, performing the gesture himself. “When she does that, that's a signal to the kids.”
