Actress Julia Roberts, known for being one of the highest-paid actors in her prime, says she isn't "ambitious".

The Hollywood's `Pretty Woman`, who has twins Hazel and Phinnaeus, nine, and son Henry, seven, with husband Danny Moder, has never harboured a grudge against anyone who landed roles she wanted, even when she was struggling for her career to take off.

"I always feel like there is room for everybody. I don't consider myself really all that ambitious. When I didn't get a part - even when I was younger and needing to pay my rent - I would think, 'Oh, someone else got it. She's going to be so good.' I never felt sour grapes,` contactmusic.com quoted her as saying.

After starring in `Pretty Woman` with Richard Gere, the 46-year-old struggled to match the success of the movie with her subsequent projects and went on to turn down a role that went on to do just as well as her breakout film, a part in `Sleepless in Seattle` which went to Meg Ryan.

Despite missing out, the actress doesn't think she would have made the role her own in the way that Ryan did.

She said: "I'd been offered 'Sleepless in Seattle' but couldn't do it. (Meg Ryan) and Tom Hanks are just such a jewel of a fit in that. I guess what they did for that moment in time is sort of what Richard and I were doing across town (in 'Pretty Woman'), you know?"
