The supermodel - who has been involved in a string of scandals throughout her career, including various claims of assault - hates to be regarded as a role model because she knows she is flawed, but insists she is trying to be a better person.
She said: "I make many mistakes. Many mistakes. I`m not a perfect human being. I have to learn from my mistakes. And a lot of the ones I`ve made have been public.
"So I always get nervous when people speak about something that sounds like a role model, because I don`t know if I`ve been a great role model myself. I don`t think I have in certain aspects of my life.
"But I`m trying to do better. I admit to my mistakes. I admit to the things that I`ve done wrong. I admit it. But I`m trying to do right by myself and my life now."
Despite her troubled past, the 40-year-old beauty says she never wallows in her mistakes but will allow herself a brief period to get herself back on track again.
She added to Interview magazine: "I don`t get depressed. When I feel an attack, I withdraw. I disappear, I replenish, and then I come back. I-m not going to wallow in self-pity and not live my life. There are always going to be some falls in life for everybody, no matter what career you have. You have to roll with the punches and keep going."
