Former X Factor judge Tulisa Contostavlos helped supply cocaine to an undercover reporter because she thought he was a Hollywood film producer who could "get her a part in a big movie," a court has heard.
The 26-year-old singer allegedly boasted she could "sort out" drugs for a man she knew as Samir Khan but who was actually Sun on Sunday journalist Mazher Mahmood, also known as the 'fake sheikh.'
Southwark Crown Court heard she was "keen to be in his good books" to get the part with Leonardo DiCaprio as her possible co-star.
She put Mr Mahmood in touch with her rapper friend Mike GLC who supplied the cocaine at a late-night rendezvous at London's five-star Dorchester Hotel last May, jurors heard.
The singer also allegedly bragged that her ex-boyfriend was a "major cocaine dealer" and she used to be part of a gang who sold crack cocaine.
Mike GLC, whose real name is Michael Coombs, 36, pleaded guilty on Monday to supplying half an ounce (13.9g) of cocaine for £860.
Prosecutor Tim Cray told jurors Tulisa was "instrumental" in setting up the deal.
She denies one charge of being concerned with the supply of class A drugs. The trial continues.
