If her debut appearance was anything to go by, the stars of Strictly Come Dancing must be wishing all the judges were like the Duchess of Cornwall.

Touring the set of the BBC1 show yesterday, Camilla watched drummer Harry Judd and partner Aliona Vilani rehearse the quickstep to The Pretenders’ Don’t Get Me Wrong – and her verdict was a definite ‘Nine!’

Prince Charles’s wife is a huge fan of Strictly and was invited to the dress rehearsal for tonight’s programme by judge Craig Revel Horwood.

During her hour-long visit she tested out Len Goodman’s seat in the judging booth and met the cast and presenters Sir Bruce Forsyth and Tess Daly.

She was particularly taken by Robbie Savage. The former footballer – who attracted hundreds of complaints for his ‘inappropriate’ hip-thrusting dance moves – was characteristically displaying his torso in a see-through blue shirt. Camilla admired his ‘wonderful teeth and hair’.

The Duchess met Revel Horwood in 2009 in her role as President of the National Osteoporosis Society.

Last month Camilla, 64, wrote in the Mail about the loss of her mother and grandmother to the fragile bone disease, which affects half of women over the age of 50. The Mail has since been campaigning for better diagnosis and treatment.

Revel Horwood, 46, a patron of the NOS, said: ‘The Duchess of Cornwall is a great president to have and we have a shared passion to spread the word about osteoporosis, which is a terrible disease.

‘My mother suffers from osteoarthritis, which isn’t exactly the same thing but has left her completely crippled.

‘She is also a former dancer but her body is bent double and her right hand is like a claw. It is so heart-breaking to see.’

Camilla’s visit came after Sir Bruce had earlier hit out at ITV rival X Factor for its ‘scripted rows’. The 83-year old told Radio 4 he thought X Factor only had ‘another couple of series in it’ before it is dropped.
