When Rihanna appeared on The X Factor last year she sparked a mass of viewer complaints because of her skimpy outfit and lewd dance routine.
To avoid a similar outcry on Sunday's show, the 23-year-old singer toned it down in a tartan pinafore and white shirt to perform No 1 single We Found Love.
But herprim ensemble wasn't quite as innocent as it first appeared - during her performance, Ri-Ri flashed the audience a peek at some cheeky stockings and suspenders underneath her girly frock.
To add to the controversy, keen-eyed viewers will also have noticed the words F*** Off painted across Rihanna's laced schoolgirl trainers.
Let's hope she'll be allowed back next year!
