The 53-year-old has admitted that he once took down a dance teacher while practising his moves.
“When I was younger I thought I’d like to do a degree in performing arts, so I went to a college for an interview and was asked to follow the teacher and do a series of moves,” he told Radio Times magazine.
“I kicked my legs in the air and took her down – she had to go to A&E.”
But Bushell said there was “no way” his troubled dance past would deter him from Strictly.
“It’s the opportunity of a lifetime,” he said. “I’m used to taking a lot of stick – so nothing worries me, really.
“Although I don’t want to frighten the nation by getting my chest out. It’s a family show.”
Professional dancer Katya Jones said she is thrilled to be partnered with “perfect” Bushell, and even teased a memorable dance to beat her salsa to Gangnam Style with Ed Balls.
“I’m excited about teaching him how to dance – I mean, what a student!” she said. “We’re here to create some iconic moves.”
