Rosie Huntington-Whiteley would love to be a physiologist.
The 27 year old beauty enjoys modelling but is fascinated by both biology and design so has diverse ideas about an alternative career.
She said: "I would love to have the patience to be an interior designer, but I also like the idea of being a physiologist."
The 'Transformers: Dark of the Moon' actress thinks it is important to set career targets and is always happy to say no to things she doesn't want to do.
Asked to give advice to aspiring models, she told online publication Violet Grey: "Keep your wits about you. Be smart. Say no if something makes you feel uncomfortable. Have goals and go after them, and practice good manners."
Rosie is happily settled with boyfriend Jason Statham and says when they visit America for work people think they are "bonkers" because of their love of cockney rhyming slang phrases.
She said: "Jason has taught me nearly the whole diction of cockney rhyming slang. I get quite a few odd looks because people don't expect it to come out of my mouth. In the U.S. people just think we are bonkers!"
The British star feels "mostly" happy and thinks true happiness comes from working on yourself and doing what you think is right.
She said: "I do believe to be happy you have to work on yourself. You have to listen to yourself and stay true to your heart."
