Her new single We Found Love is already sitting above the UK and US charts, but Rihanna is still working overtime to promote the dance-pop track.

The 23-year-old singer stopped by the X Factor tonight and set pulses racing in a naughty schoolgirl-style get-up.

She wore a red tartan dress with metal-tipped collar and laddered stockings.

While her cute frock was far more covered up than the racy outfit that sparked complaints last year, Rihanna managed to inject her usual cheeky, provocative style.

Rihanna's energetic performance of the song, currently topping the charts in the UK, turned the studio into a dance party.

The superstar told Dermot O'Leary afterwards that she was considering moving to London after performing so many shows in the UK this year.

Despite hitting number one around the world, We Found Love, a collaboration with Calvin Harris, has not been without controversy.

Last week the Rape Crisis Centre labelled Rihanna a 'disgrace' for the raunchy music video, which sees the singer being spanked by her real life boyfriend Dudley O'Shaughnessy, who also pens the word 'mine' on her behind.

Speaking to the Daily Star, a spokesperson for the centre said: 'Rihanna's new video is a disgrace. It sends the message that she is an object to be possessed by men, which is disturbingly what we see in real violence cases.'

Returning home: Last year's runner-up Rebecca Ferguson performed her debut single Nothing's Real But Love

Before Rihanna stormed the stage, Rebecca Ferguson made her return to the show to perform her debut single Nothing's Real But Love.

Last year's runner-up looked sophisticated in a black high-neck dress with gold embellishment and her long hair out in cascading waves.

'It was quite nerve-wracking but I feel like I'm back at home,' said Rebecca, who co-wrote her upcoming album.
