Paris Hilton's 'empty' life

Paris Hilton says partying left her feeling "empty inside".The hotel heiress - who spent 23 days in jail for driving offences in June - is now determined to change her life around and do worthy things instead of being seen falling out of nightclubs.She told Us Weekly magazine: "Before, my life was about having fun, going to parties - it was a fantasy. But when I had time to reflect, I felt empty inside. I want to leave a mark on the world."Paris is starting her search for fulfilment next month.She is set to visit Rwanda with children's charity Playing for Good and will be filming her experience for a revealing documentary.She said: "I'm scared, yeah. I've heard it's really dangerous. I've never been on a trip like this before."I love having everything documented. It shows people what everyday life is like for me, how hard I work."

Last month, 'The Simple Life' star revealed she is planning to visit Rwanda in the hope of using her fame to draw attention to the plight of the war-torn African country.

Paris, 26, said: "I'll be going in November, after I get back from filming my movie.

"There's so much need in that area, and I feel like if I go, it will bring more attention to what people can do to help.

"I want to visit more countries where poverty and children's issues are a big concern.

"I know there's a lot of good I can do just by getting involved and bringing attention to these issues."
