Rihanna is the latest celebrity to take a swipe at troubled stars like Britney Spears and Lindsay Lohan, saying that no one can help them but themselves.

The Umbrella singer thinks that the rehabbed stars are not doing enough to help themselves and thinks they should get their lives in order.

She tells the British edition of 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."

Will Rihanna fall down the same route as these troubled stars and be eating her words in years to come?
