Teen star Miley Cyrus, who recently caused controversy with some risque photos, is defending Lindsay Lohan and Britney Spears saying it is 'normal' for the young stars to act wild some times.

The 15-year-old says Lohan and Spears have 'good hearts', contactmusic.com reports.

She said: 'Everyone has their time. And I think most 21 to 25-year-olds go through this kind of thing. Basically, they're being normal 21-year-olds, especially Lindsay. I mean, most of that's pretty normal.

'If you went to most high schools, I could point out Britneys and Lindsays. I guess that's why I'm so adamant about the Britneys and Lindsays and whatever, because I know those people and I know they have good hearts and they're just struggling.'
