Singer Tulisa Contostavlos has walked free from court after her trial collapsed.
The N-Dubz star and former X Factor judge, who lives in Friern Barnet, was alleged to have brokered a deal to supply cocaine to an undercover reporter.
Miss Contostavlos, 26, denied the accusations.
Today at Southwark Crown Court, Judge Alistair McCreath dismissed the jury after telling the court there were "strong grounds" to believe the undercover reporter, Mahzer Mahmood, had "lied" during a previous hearing.
Miss Contostavlos' co-defendant, Michael Coombs, 36, of Velocity Way, Enfield, had earlier pleaded guilty to supplying the class A drug. He is currently on bail ahead of sentencing.
