Rihanna to kick-off 'X Factor' Boot Camp

Rihanna is set to perform at the ‘X Factor’ Boot Camp.

The ‘S & M’ hitmaker – whose performance during the live episodes of the TV talent show sparked nearly 3,000 complaints last year for being too raunchy – has been invited to the programme to kick off the second round of the contest, piling on more pressure for hopefuls who will be forced to take the stage to audition after she sings.
