Rory Bremner says he woke up so terrified of forgetting his Strictly Come Dancing routine that he prised himself out of bed to rehearse it in the middle of the night.
The impressionist, 50, who has lost half a stone in weight and two inches from his waist since joining the BBC1 show, said it had taken over his ‘waking hours’ and some of his ‘sleeping hours’ too.
He told the Radio Times: “Two nights before my waltz, I woke in a muck-sweat, panicking that someone had broken into my head and taken out the file marked ‘choreography’.
“I got up, plugged in my iPod and danced around the bedroom, bouncing off the furniture.
“Every time I spun around, the iPod jumped to the next tune, a salsa. After half an hour of waltzing to a combination of Barry Manilow and hot salsa … I slumped back into bed, exhausted.”
Rory, who scored 31 out of 40 with professional dancer Erin Boag on this weekend’s instalment, added: “I’ve grown accustomed to the pitying looks I get when my wife catches me yet again checking my frame, my line or my footwork.
“You can’t help it. The supermarket, the hotel room, the train platform, all become an imaginary dance floor”.
