(Cover) - EN Showbiz - Rosie Huntington-Whiteley says people expect her to be a "huge b***h".

The 24-year-old model claims many are surprised when she first meets them. The stunning star thinks it's funny that people anticipate her not being so nice in person.

"People always tell me, 'Gosh, you're so nice!'" she quipped in an interview with the July/August edition of Women's Health. "Like they expect me to be a huge b***h!"

Rosie famously replaced Megan Fox in the lead female role opposite Shia LaBeouf in the upcoming instalment of Transformers: Dark of the Moon. Rosie says Shia was quick to warn her of the arduous filming schedule.

"Shia [LaBeouf] made it clear this wasn't just about becoming a movie star. The shooting schedule was going to be gruelling," she explained. "You're in the sun all day long. It was like boot camp."

Rosie has also revealed she prefers organic food. The beauty, who confessed her love for British meals recently, often thinks about the chemicals in processed foods when she's doing her regular groceries shop, and is instantly put off.

"[I'm always] thinking about the things that go into processed foods - chemicals, additives," she said. "Sometimes you go into a supermarket and the apples are all the same size and colour, but that's not what apples are supposed to look like. Go to an orchard or an organic farm, and the apples are sometimes knobby, but they taste better." (C) Cover Media
