Her lewd behaviour has brought savage criticism in recent weeks.

But if Rihanna thought there was a need to tone things down in public there was no sign of it at the O2 Arena last night.

The 23-year-old singer stunned the London audience as she worked her way through a provocative routine.

She initially arrived wearing a bottom-skimming blue jacket but quickly stripped down to a barely-there jewelled bikini, nude fishnets and neon platform boots.

Just days ago, farmer Alan Graham ordered the Barbadian singer off his land after she stripped down for a music video.

The 61-year-old interrupted filming on his muddy field in Northern Ireland and warned the star, who was wearing low-slung jeans and a bikini top, to ‘find a greater God’.

Days later, the singer was warned she would have to cover up if she appeared on The X Factor again, following thousands of complaints over her skimpy outfits on last year’s show.

TV watchdog Ofcom announced stringent guidelines for pre-watershed programmes, putting an end to scantily-clad dancers and overtly sexual routines on the ITV talent contest.

Earlier in the day Rihanna impressed fans by taking the Tube to her concert.

One fan took a photo of the singer on the city’s Jubilee line and uploaded it on a  photo site.

Along with the picture, fan Lisa Maria O’Keeffe wrote: ‘I met Rihanna on my way home. Told her she was crazy for taking the tube.

She said “Dunno how you guys do it”.’
