X Factor judge Tulisa has been named FHM's 'Sexiest Woman in the World' for 2012.

The N-Dubz singer beat-off stiff competition from other famous popstars like her predecessor Cheryl Cole, who won the title in 2009 and 2010 and Rihanna, who was a non-mover from last year's vote at three.

Glamour model Rosie Jones and Celebrity Big Brother star Georgie Salpa round out the Top Five.

The men's magazine presented Tulisa with her award at an event held at London's Proud Cabaret club.

Speaking about her victory, Contostavlos declared: "It's a true honour and definitely a lovely confidence boost. I'm proud of me and I am who I am. I know that I'm marmite and I wouldn't wanna be anything less or anything more, I'm just myself."

In ninth place was Mila Kunis who had previously sat at 16 and The Inbetweeners star Emily Attack moved up from number 18 to tenth place.

Irish model Georgia Salpa was also there after ranking 5th on the list

Following on from the Royal Wedding exactly a year ago, Pippa Middleton ended up at No.11, while her elder sister Catherine, Duchess Of Cambridge was at No.32.
