Little Mix have revealed that they were forbidden to chat to Rihanna after she took to the 'X Factor' stage last year prior to the girl band's spectacular win.

The 'DNA' hitmakers insisted that Ri Ri's management prevented any contact between the star and the contestants. 'Her management wouldn't let anybody meet her, but she walked past me and said, 'Your hair is awesome!' This was when I had my head half-shaved, which I hated, so it cheered me up', Leigh Anne Pinnock told We Love Pop magazine. They also shared the stage with Lady GaGa who was apparently a lot easier to talk to. 'Lady Gaga was amazing', said Jesy Nelson. 

Being new on the pop scene, that wasn't the last time they were to be a little starstruck by their fellow pop icons as they recently got the chance to meet Aussie singer Kylie Minogue. 'We met Kylie at the BRITs', said Jesy. 'I kept looking at her bum because she's got a really nice bottom.' The girls hope, however, that they'll be the ones the other stars are dying to meet revealing that they plan to become the world's biggest girl band within the next three years. 'You've got to aim high', Leigh Anne added.
