Singer Tulisa Contostavlos is expected to make her first appearance at Crown Court today accused of brokering a cocaine deal.
The N-Dubz star is charged with helping an undercover reporter for the Sun on Sunday to obtain 13.9 grams of the Class A drug for £860.
Contostavlos, of Friern Barnet, north London, denies being "concerned with the supply of 13.9 grams of cocaine" to Mazher Mahmood between May 20 and May 24.
She is listed to appear alongside rapper Mike GLC, also known as Michael Coombs, 35, of Velocity Way, Enfield, north London, who denies a charge of supplying the drug on May 23.
Both will appear at a preliminary hearing at Southwark Crown Court.
