Penny Lancaster is running dance partner Ian Waite ragged in a bid to waltz to victory over rival Kelly Brook.
Rod Stewart’s stunning blonde wife has been badgering Ian for extra practice time to make sure her Hot Legs triumph.
Penny, 36, is desperate to upstage beautiful fans’ favourite Kelly, 27.
She is being backed by Rod – a familiar face at her side in rehearsals.
Penny and Ian want their first dance to be the hardest ever on the show.
A BBC source said: “Penny is determined to be the best. Even when Ian stops she wants to carry on rehearsing.”
