Bottoms up! Miley Cyrus spanks towering dancer's behind during raunchy stage performance

She is undoubtedly the cheekiest woman in pop.

So it will come as no surprise Miley Cyrus is hard at work perfecting the raunchy new stage show she is preparing to unleash on the UK as part of her latest world tour.

The slap happy singer seemed to revel in spanking a towering backing singer's behind as she hammed it up during her concert at the Los Angeles Staples Centre on Saturday night.

She is currently in the middle of a North American leg that will see her perform in the likes of Las Vegas, Houston, New Orleans and Miami.

Mile has caused controversy miming a sex act on a man wearing a Bill Clinton mask, groping her backing dancers and wearing a glittering leotard seemingly decorated with cannabis leaves.

Her racy routines have already made waves, with her concert promoters forced to deny her new Bangerz tour was in jeopardy due to to complaints from outraged parents.

A spokesman for promoters Live Nation said: 'There is no truth whatsoever to any stories or rumors of venues pulling out of the Bangerz Tour.

'Miley has created a tour that's big, spectacular, entertaining and everything you would expect from Miley Cyrus.

'Reviews have been amazing and most important, fans are loving the show and having a great time.'

The 21-year-old also addressed the rumours herself on Twitter, saying: 'You can't say I didn't warn you. Now sit back relax & enjoy the show. #bangerztour.'

The Wrecking Ball singer is performing in London, Leeds, Glasgow, Manchester and Birmingham in May when she tours Europe.

However, while her antics are getting lots of publicity for the singer, it seems it may not be doing the former squeaky clean Disney kid much good.

For it has been claimed ticket sales are dwindling due to concerned parents not wanting their children to see the former Hannah Montana star's racy on-stage behaviour.
