Rosie Huntington-Whiteley was an "Ugly Betty" as a teenager.
The 24-year-old British beauty is widely considered to be one of the sexiest women in the world but when she was growing up she admits she resembled the spectacle and brace wearing character Betty Suarez from the TV series.
Speaking in the new issue of America's Harper's Bazaar magazine, she said: "I was a bit of an Ugly Betty when I was 15."
Rosie revealed she would arrive at castings "in trainers, with braids, a ton of make-up, plucked eyebrows and I had braces".
The catwalk star - who is dating Jason Statham - recently made the transition from modelling to acting with a main role in Transformers: Dark of the Moon and she admits she initially found it difficult to adjust to the movie business.
