Mila Kunis took top position in the FHM poll, while Georgia Salpa fell to tenth position.
Kunis who is dating actor Ashton Kutcher took top place in the annual 'FHM' 100 Sexiest Women in the World poll.
Irish model Georgia Salpa who came in fifth position last year, has dropped five places to number 10. She was on the red carpet last night in London for the FHM party where the full list was announced.
Helen - who took part in last year's I'm A Celebrity and was forced to undergo a series of bushtucker trials - said: "It's a lovely confidence boost, especially when there are so many beautiful girls out there."
Singer Rihanna takes the runner-up spot, rising one place from her 2012 result.
Kelly Brook - who topped the poll in 2005 but was down to number 20 last year - has bounced back to fifth position.
Interior designer Linda Barker - who braved both the high-diving board and a bikini to take part in ITV's Splash - is at number 93.
The full list is included in a supplement to the June edition of FHM magazine. Editor of the section Dan Jude said of winner Mila "Not only is she naturally stunning, but she has a great sense of humour and isn't afraid to poke fun at herself. The nation has spoken, and the verdict is that she is officially the perfect girlfriend. She'll take some beating in 2014."
