Strictly Come Dancing celebrity Jade Johnson has said the show is now so raunchy that it should be on after the 9pm watershed.

The Olympic athlete told The Sun that the sexual tension between the dancers and their professional partners had reached “fever pitch”.

There has already been speculation that boxer Joe Calzaghe and his partner Kristina Rihanoff are now an item, while Brian Fortuna told the paper earlier in the week he was “desperate” to go on a date with his celebrity partner Ali Bastian.

Jade – who is dancing with professional Ian Waite, said, “Strictly is so hot it should have a late night version. You can’t help get close whether it’s in a sexual way or in a ‘relying on you’ way.”

“I have had family members in the audience next to the partners,” she added. “Every time they see a hand run up a thigh they jump in their seat.”

And Waite agreed. “Dancers are very touchy-feely,” he said. “You are supposed to show sexual desire.”

Saturday’s show will see all 14 remaining couples go head to head for the first time, performing either a Paso Doble or a a href=”http://en.wikipedia.org/wiki/Quickstep”>Quickstep in a bid to remain in the contest.
