Actress-singer Jennifer Lopez defends Britney Spears, Paris Hilton and Lindsay Lohan and says they have problems because they cannot cope with fame and excessive media attention.

Ananova.com quoted her as saying: 'People wonder why Britney or Lindsay or Paris is acting crazy, but they don't know what it means not to be able to walk outside your house. 'Oh, but she has millions!' they say, but that doesn't help when you can't...feel good.

'I feel so bad when I see people going through the beginnings of it because it's not fun. You have to learn to navigate it because if you don't, it will eat you up. It's a lot of pressure. And you gotta keep grounded and find a way to deal with it and hopefully have love in your life.'
