Spears' dad blasts ex-manager

Britney Spears' father Jamie has blasted her former manager Sam Lutfi - accusing him of spiking the singer with drugs and wrecking her life.

Jamie Spears, the co-conservator of his daughter's estate since January 2008, is seeking to extend a restraining order against Lutfi and the 'Toxic' hitmaker's ex-boyfriend Adnan Ghalib, making it a permanent injunction.
