Rosie Huntington-Whiteley thinks of herself as ''a business''.

The model-and-actress - who is in a relationship with actor Jason Statham - admires the work ethic of supermodel Gisele Bundchen and has learned a lot in her approach to work from her.

She said: ''I love Gisele. She has such a healthy image and has made herself into a brand.

''I guess I try and think of myself as a business. And I want to go to work.''

Rosie thinks having a ''strong personality'' is key to success in the fashion world, but she hates the fact she can be thought of as ''a bitch'' because she isn't afraid to speak her mind.

She added in an interview with Sunday Times Style magazine: ''You have to have a strong personality, to be able to pick yourself up and dust yourself off and you have to find your voice pretty quickly to be able to say no and stand up for yourself.

''When a woman wants something and she goes about it in a tough way, a lot of the times she gets branded a bitch. That p***es me off because when a man is firm, he's just doing his business. But I definitely don't go around stomping my feet and shouting.''
