The Australian stunner shares the Esquire crown with Mila Kunis, who was named America's Sexiest Woman last month (Oct12).
The Victoria's Secret angel, who is a new mum, graces the cover of the new men's magazine wearing nothing but a pair of purple panties.

I don't really think of rules, as long as it's classy and timeless and it's something I wouldn't be ashamed of. I believe in celebrating the female figure and embracing what we've been given.""
