Mariah Carey's awkward onstage lap dance

Mariah Carey gave a man a very awkward lap dance onstage in South Africa.

Dressed in a black sequinned leotard showing off her svelte body, Mariah straddled dancer and choreographer Bryan Tanaka during her performance of song Touch My Body.

Bryan was brought onstage by his fellow dancers, blindfolded and sat on a chair as Mariah dramatically tossed herself backwards and from side to side as she sat in his lap.

Grabbing his hands to hold her she flung herself backwards so violently, the dancers flanking Bryan reached out in fear she might fall.

The lap dance was made that bit more awkward by the fact that the dancer's left leg is heavily strapped because of an injury to his patella.

The choreographer, who has worked with Beyonce, posted a picture on Instagram with the caption: "bryantanaka I asked for a bag of ice and got this... My offical diagnostic is a #FracturedPatella Out for 4-6 weeks. It's unfortunate but you won't hear me complaining too much. There's a lot to be grateful for. #Life (sic)".

Newly engaged Mariah was performing in Johannesburg at the final show of her Sweet Sweet Fantasy Tour. The 46-year-old ended the European leg of the tour in Amsterdam last month (Apr16). But things didn't go exactly to plan.

She took to the stage 45 minutes late telling the audience that she had been held up due to celebrating her "dear friend's birthday". Then her performance was interrupted by her complaints about the electric fans that adorned the stage.

The mother-of-two has also been filming preparations for her tour and life on the road for her highly anticipated reality show Mariah's World.

"Mariah is looking forward to a break after travelling the world on her tour," a source told Britain's Daily Mirror newspaper. "She’s worked really hard and she has also had the cameras capturing every detail backstage, too."
