It's one blow after another as pop star Britney Spears sinks lower into despair and attempts suicide.

Last week it emerged she was seeing a psychiatrist for 'mental problems', but insiders now fear her friendship with two manipulative, controlling men is killing her.

Friends say her relationships with manager Sam Lufti and photographer Adnan Ghalib are 'tearing her apart' and could be at the heart of her apparent suicide attempt.

The latest cry for help is a clear indication to family and friends that they need to intervene on Britney's behalf and get her the professional help she so desperately needs.
