Tulisa has usurped Rosie Huntington-Whiteley and Cheryl Cole to be named the world's sexiest woman.
The X Factor judge, 23, who recently hit the headlines when a sex tape appeared online showing her sharing an "intimate moment" with a former boyfriend, tops the annual FHM list.
Two-time winner Cheryl takes second place, followed by pop star Rihanna and glamour model Rosie Jones.
Model and Transformers star Rosie drops down to 18th place from top of the list in 2011.
Irish model and Celebrity Big Brother contestant Georgia Salpa is fifth, followed by US pop star and Russell Brand's ex Katy Perry. Actress Megan Fox, glamour model Keeley Hazell, Friends With Benefits star Mila Kunis and Inbetweeners actress Emily Atack complete the top 10.
Pippa Middleton makes FHM's 100 Sexiest Women In The World list at 11, while her sister the Duchess of Cambridge is 32nd.
Singer Pixie Lott is 12th, followed by model Daisy Lowe (13), and The Saturdays singer Mollie King (14). Her bandmate Frankie Sandford is 19.
The top 20 is completed by Made In Chelsea star Millie Mackintosh (15), The Voice judge Jessie J (16), actress Zooey Deschanel (17), and model Kelly Brook (20).
"I'm proud of me and I am who I am. I know that I'm Marmite and I wouldn't want to be anything less or anything more, I'm just myself," Tulisa said. "This is an award that will stay on the mantelpiece probably for the rest of my life."
The full list, voted for by FHM readers, comes with the June edition of FHM, on sale now.
