2011: Bruno Mars performs ‘Runaway Baby’ on The X Factor results show

Bruno Mars made his X Factor debut on tonight’s live results show.

The American sing songwriter has never before appeared on the ITV show, but this evening took to the stage to sing one of his album tracks ‘Runaway Baby’.

With the lively up tempo track, Mars put on quite a show that reminded us of some of the American music legends of the past as well as James Brown.

Mars was also a man in a hurry; an hour after he taped his live X Factor performance, he was due to kick off a concert in London’s O2 Academy Brixton.

However, he still managed to find time to chat with some of the X Factor contestants backstage though and The Risk were especially pleased to see him, after he praised their rendition of his song ‘Just The Way You Are.’ They took to Twitter to reveal:

“Wow, @BrunoMars just stopped on the way to the stage and said we done a good job on his song last week #AbsoluteLegend”
