The Bajan 23-year-old performed her number one single We Found Love while wearing a demure tartan pinafore dress with buttoned-up collar, and her hair tied in a bow. But her punk-style shoes, daubed with scrawled writing, had the words "F*** Off" written on them. Fan Lucy Morgan, 18, told the Sun: "It was cheeky. I was shocked."Her prim outfit at first made it seem that Rihanna had toned down her act last night after her appearance on the same show last December in a provocative costume left little to the imagination and led to thousands of complaints.
Broadcasting watchdog Ofcom later cleared the X Factor for family audiences but in September set out new guidelines ordering that programmes shown before 9pm should not feature skimpy outfits or raunchy performances.
Earlier this year, Rihanna fell foul of a Northern Ireland farmer who objected to her "inappropriate" attire as she filmed the video for We Found Love in his field near Bangor, County Down. Meanwhile X Factor contestant Craig Colton, 23, was kicked off the show last night after the show after a public vote.
