The former 'Coronation Street' star was voted the top Brit, coming in at number three, behind winner Mila Kunis and runner-up Rihanna.
H-Flan also fended off stiff competition from her former 'Corrie' co-star Michelle Keegan, who polled fourth overall.
Posing for a sexy spread inside the new issue of FHM, she proved exactly why she ranked so highly.
Commenting on being voted the UK's sexiest woman, she said: "I'm absolutely thrilled to be voted the Sexiest Woman In the UK. It's a lovely confidence boost, especially when there are so many beautiful girls out there. Rosie Webster would definitely be impressed!"
Helen stole the Brit crown from Tulisa, who ranked first overall in 2012, and slipped to 11th this year.
