(Cover) - EN Showbiz - Rosie Huntington-Whiteley doesn't care much for the reasons behind her landing her big break in the new Transformers movie.

The British model-and-actress, best known for modelling for Victoria's Secret, replaced Hollywood siren Megan Fox as the lead female character in the upcoming film Transformers: Dark of the Moon.

The 24-year-old beauty stars opposite Shia LaBeouf as his new love interest in the Transformer franchise's third movie after the announcement that Megan would not be reprising her role as Mikaela Banes.

Rosie says she hasn't given her big break much thought.

"That's a question for the filmmakers," she said in an upcoming issue of Complex magazine when asked how her role opened up. "I haven't given it much thought."

The beauty has also revealed the secret behind her sultry strut. The star says she learnt to walk on a runway at the age of 16 from two Jamaican male roommates in London. She has revealed their guidance was invaluable to perfecting her runway walk.

"Gay men are usually pretty good at the model strut," she added. (C) Cover Media
