Strictly Come Dancing
Strictly Come Dancing has been hit with a porn scandal before the show even startsBBC

The opening sequence for the new series of Strictly Come Dancing, hitting TV screens 5 September, features a train used in a pornographic film for the X-rated internet site Brazzers.

The Strictly crew filmed the opening sequence this past weeekend, at Epping Ongar railway station. The clip sees the show's professional dancers performing a routine alongside the 'Strictly Express' train to the tune of Kylie Minogue's Locomotion. The dancers are then rounded up by a guard, played by judge Craig Revel Horwood, before they depart for Elstree Studios, where they will start the show live.

However, the 'Strictly Express' was used in 2014 by the adult website Brazzers for their movie Nympho. The porno flick centres around a young woman who has sex with a man on her way to school, back in the 1940s. The twosome have intercourse in one of the train's wood-panelled train carriages.

The link to the x-rated film is an embarrassment to the show's family-friendly image. Talking to The Sun, an insider claimed: The BBC prides itself on Strictly being good clean fun. Everything about it is so safe and wholesome. So this will come as a horrible surprise. To be fair to Strictly, they could have had no idea."

In non-Brazzers news, the BBC have revealed that Bruce Forsyth will be hosting two episodes of this year's series: the Children In Need special and the Christmas show. The 87-year-old showbiz icon stepped down last year as the show's frontman, handing over duties to Claudia Winkleman and Tess Daly. He did still appear three times last season, so these cameos are not a major shock.

Strictly Come Dancing 2015 is on TV this Saturday (5 September) at 7.15pm, where it will be publicly announced which professional dancer each star will be paired with. Celebrities taking part in the show include: broadcaster Jeremy Vine, weather presenter Carol Kirkwood, The Wanted's Jay McGuiness, pop star and Loose Woman Jamelia, boxer Anthony Ogogo and journalist Anita Rani.

Also joining them will be television chef Ainsley Harriott, Eastenders actress Kellie Bright, TV and radio presenter Katie Derham, singer Daniel O' Donnell, Coronation Street star Georgia May Foote and cross-media personality Peter Andre. Call The Midwife actress Helen George, Sky Sports presenter Kirsty Gallacher and athlete Iwan Thomas were the last contestants to be announced.
