'Marilyn Margot': I was an ugly duckling

Despite channelling Marilyn Monroe on the cover of Vanity Fair , Wolf of Wall Street star Margot Robbie says she did not feel attractive growing up.

''I am definitely not the best-looking,'' the 24-year-old told the magazine.

''You should have seen me at 14, with braces and glasses, gangly and doing ballet!''

According to Britain's Daily Mail, Robbie, who was born in Queensland, Australia, features in Vanity Fair's August issue.

She is among an elite group of actors to feature on Vanity Fair's cover, including Monroe, Audrey Hepburn, a heavily pregnant Demi Moore and Brad Pitt and Angelina Jolie.

According to the Daily Mail, Robbie, who got her break in Neighbours, will play Jane in a new 3D Tarzan movie starring Alexander Skarsgard.
