X Factor winners Little Mix, who this week scored their first ever Top Ten album with debut release DNA, have revealed that Rihanna's management made sure the US star did not mix with the talent show hopefuls.

The reality show stars were thrilled to be performing on the same stage as the 'Diamonds' star, but were disappointed to find out that Rihanna's management would not let anyone speak to her during her guest appearance on last year's X Factor competition.

Little Mix member, Jesy Nelson said it was difficult to get anywhere near Rihanna, but Lady Gaga was a lot more approachable backstage: "We were on 'The X Factor' with Rihanna and Lady Gaga. Lady Gaga was amazing, but we didn't get to speak to Rihanna."

Rihanna topped the UK album chart this weekend with her latest set Unapologetic, while Little Mix landed at number three with their debut DNA.

RiRi did manage to have an impact on one of the Little Mix singers. Leigh-Anne Pinnock added: "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."

Little Mix, who became the first group to win The X Factor in 2011, had much more flattering things to say about Austrailian pop star, Kylie Minogue. Jesy told, We Love Pop magazine: "We met Kylie at the BRITs. I kept looking at her bum because she's got a really nice bottom."
