Rosie Huntington-Whiteley has spoken exclusively to Total Film about appearing in Transformers: Dark of the Moon .
The British supermodel is making her movie debut in Michael Bay's threequel, but she has worked with the director before on a Victoria's Secret campaign.
On her character, Carly, Huntington-Whiteley tells us: "She's English and is working for the British embassy... I can't tell you more! That's all I can say for now!"
Huntington-Whiteley was cast as Sam's (Shia LaBeouf) new girlfriend after Megan Fox left her breakthrough franchise.
"I went to the casting unaware they were looking for a new female lead", says Rosie.
"We were told it was for a 'nemesis' role and I left thinking I was awful. The next day I was offered the lead!"
"I met with Shia that evening and within three weeks I was on set shooting my first scenes..."
Transformers: Dark of the Moon hits UK cinemas on 1 July 2011.
