Former X Factor judge and N-Dubz singer Tulisa Contostavlos has denied being involved in the supply of drugs.

Miss Contostavlos, who lives in Friern Barnet, appeared at Westminster Magistrates Court this morning where she pleaded not guilty to being concerned in the supply of class A drugs.

Michael Coombs, 35, from Velocity Way, Enfield, also appeared charged with the supply of class A drugs, but he did not make a plea.

The pair was given unconditional bail and will appear at Southwark Crown Court on January 9.
