The trial of Tulisa Contostavlos over drugs allegations has collapsed, Press Gazette reports.
The singer was accused of boasting that she could "sort out" cocaine for a journalist and put him in touch with her rapper friend Mike GLC, who supplied the Class A drug.
Undercover reporter Mazher Mahmood, dubbed the "Fake Sheikh", posed as a wealthy film producer called Samir Khan when he met the former X Factor judge at a string of luxury hotels and restaurants, jurors at London's Southwark Crown Court heard.
Contostavlos vehemently denied brokering the deal, which was exposed in the Sun on Sunday newspaper last June.
Today judge Alistair McCreath told the jury that the case "cannot go any further" because there were "strong grounds to believe" that Mahmood had "lied" at a hearing before the trial started.
After hearing the news, Contostavlos urged police to investigate Mahmood and "put an end to his deceits".
