Renee Zellweger has admitted that she sympathises with young stars who have just started their movie careers.

The actress explained that many Hollywood stars are not yet old enough to be able to deal with negative comments in the press and on the internet.

"If you're entering this business right now, there are blogs and so many opinions that are given. That is complicated," Zellweger is quoted by the Evening Echo as saying.

"I don't understand our insatiable appetite for negativity in the press and I'm really glad not to have entered into this business really young."
