The former Coronation Street actress, 27, was runner-up last year but this time she's topped the poll for 2015, triumphing over the likes of Jennifer Lawrence, Kendall Jenner, Kate Upton and Caroline Flack.
FHM said: "She's one of the most mind-bendingly sexy women ever to step foot on British telly, and the votes proved it."
Someone who definitely agrees with Michelle winning the poll is her fiancé Mark Wright, who couldn't help bragging a bit about his gorgeous other half.
