Rihanna performed her latest single 'We Found Love' on last night's X Factor.
The singer took to the stage, wearing a naughty schoolgirl outfit and shoes with the words 'f*ck off' written on them as she belted out the Calvin Harris-produced track.
Last year more than 2,750 people complained about Rihanna and Christina Aguilera's routines on the show, which featured revealing costumes and scantily clad backing dancers.
Many upset viewers also contacted Gigwise, with some comparing the performances to "soft porn".
Rihanna has also recently been criticised by the Rape Crisis Centre for her latest music video
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.'
