Despite being the epitome of a pin-up, Holly Valance claimed she is 'not sexy' on last week's Strictly Come Dancing episode.

However, these pictures of her practicing with Artem Chigvintsev for their Tango look sizzling.

Considering Holly is dressed in her training clothes, including a shabby grey T-shirt, viewers are likely to be bowled over when she pulls off these moves in her revealing stage costumes.

The former Neighbours star, 28, is hot on the heels of 43-year-old Jason Donovan, who is currently dominating the leader board after coming top in two consecutive weeks.

Last Saturday, the Kiss Kiss singer scored an impressive 30 out of a possible 40 for her Salsa.

After revealing her insecurities about her sexuality, judge Alesha Dixon said: 'Please don't question if you are sexy or not. You are a goddess! Don't be afraid, just let go. You could be amazing.'

Bruno Tonioli agreed, adding: 'You are a stunner with a capital S. You're like a Formula car when you put her on the road, you need a few laps to get her going, but you've got plenty of mileage.'

Harry Judd on the other hand, appears to have taken a step backwards in the looks department.

The McFly star has been sporting some dodgy sideburns as he and partner Aliona Vilani impersonate John Travolta and Olivia Newton John.

The couple have stepped into the shoes of T-Bird and Pink Lady for their Jive tomorrow.
