Strictly's Andrew Castle reveals the naked truth of how he practises his moves

GMTV presenter Andrew Castle shocked the judges and his fellow Strictly Come Dancing contestants when he admitted that he practises his dance moves around his bedroom at night - naked.

He made the admission on Saturday night's show during his post-performance interview with Tess Daly.

The former tennis star's admission made his fellow contestants crack up with laughter. He then went on to explain that his preferred practice method 'allowed for better freedom of movement'.

Naked ambition: Andrew Castle with dance partner Ola Jordan

A startled Daly then said : 'Hmm, that paints a lovely mental image'.

But Arlene Phillips didn't appreciate Castle's candour accusing him of offering 'Too much information'.

But despite his naked ambition, Castle and dance partner Ola Jordan failed to impress the judges with his tango which included a strange 'headbanging' movement in the middle of routine, that prompted some giggles from the audience.

Phillips also commented on his posture calling him 'the leaning tower of pisa'. She added: 'I've never seen headbanging in a tango before.'

Len Goodman wasn't a fan of it either: 'I didn't like the headbutt thing but it was a jolly good try'.

Tonioli was also disappointed with Castle's posture likening him to a 'house with subsidence, held together by hope'.

The pair scored just 22 points out of 40 but that was still four more than Gary Rhodes.

The chef scored lowest of all the male contestants whose turn it was to dance this week, attracting just 18 points.

Rhodes admitted he'd had a stressful week and felt an immense amount of pressure to perform.

Judge Arlene Phillips told Rhodes: 'You've got to stop counting and just feel the rhythm...It was as flat as a pancake.'

Bruno Tonioli was equally scathing saying: 'Your jive had more holes than the surface of the moon.'

Craig Revel Horwood said he thought that it hadn't been a 'complete dance disaster' but admitted he'd 'been praying for you for the entire time'.

Len Goodman was kinder saying the performance was like eating in one of Rhodes's restaurant - 'a lovely starter'.

Meanwhile the rivalry between rugby player Austin Healey and Holby City's Tom Chambers continued apace with both celebrities performing excellent jive dances that delighted the judges.

King of spins: Tom Chambers and Camilla Dallerup

Healey came top of the board with 34 points although not all of his performance went down well with the judges.

'I find it off-putting when rugby players wink at me,' scolded Len Goodman. But Phillips said she 'loved it'.

Hot on Healey's heels was Tom Chambers with 33 points.

His and Camilla Dallerup's routine made Tonioli gush: 'You're a bright-eyed, bushy-tailed master of spins!'

Impressive: The female contestants peformed a swing dance together

The female contestants didn't perform this week but they did entertain the audience with a swing dance routine that was so polished it prompted Len Goodman to say that it was the best group dance ever performed on Strictly.

The results of the public vote will be announced on the second part of Strictly Come Dancing on Sunday at 8.10pm on BBC1.
