Mischa Barton has admitted that becoming famous as a star of ‘The OC’ made her “"vain and self-obsessed".
But the 20-year-old actress says she addressed the problem as soon as she realised her ego and attitude were spiralling out of control.
“I was becoming too high maintenance,” she says.
Mischa has revealed that she felt she had to stay grounded, too allow her fans and viewers to connect with her more.
"Actors will start talking about themselves as if they're the most important people on Earth - and I was no different,” she says.
"We have to have a big belief in ourselves. For most of us it's all about 'me, me, me'. It's a mad business.
"You play so many characters, and have to try to almost become them, that the self-absorption can take over your life.
"The moment you have success, people give you things, they make a fuss and try to make your life easy. And the younger you are, the worse it can become.
"At times I've thought to myself, 'I deserve this.' But I don't deserve anything at all. I'm 20 for goodness sake."
