Rihanna: 'Spears, Lohan it's your fault'

Rihanna has told Britney Spears and Lindsay Lohan that they are to blame for their recent problems.

The singer has claimed that the young pair's recent brushes with the law and drug-related issues can only be solved by them helping themselves.

She told Cosmopolitan: "There's nothing I can say that'll change their minds about their lifestyles.

"They have to make the change for themselves and I don't know if they want it bad enough."
