PARIS HILTON has hit back at critics who think she doesn't do much for a living.

"I think that people don't realise that I work very hard, and there's a lot of work that goes into it," she told MovieFone.com. "It's not just showing up and looking pretty – there's a lot of business and decisions that have to be made every single day.

"It's a lot of pressure having to be in the media and constantly scrutinised, you know, when all you're doing is trying to be a good person and live your life."
