The former X Factor judge was pictured outside Southwark Crown Court in London and looked sombre in an all-black outfit.
Unlike her previous appearance, which was connected to this case, Tulisa wore her hair in a neat bun and toned down the make-up.
Back in December, Tulisa sported a head of big blonde curls and lashings of lipgloss for a hearing at the same court.
Today's appearance was for a plea and case management hearing and, after a legal discussion, the case was adjourned until 25 June.
Tulisa was released on bail. Her trial is scheduled to begin on 14 July, the day after Tulisa's 26th birthday.
In December, Tulisa appeared at Westminster Magistrates' Court and denied being involved in the supply of Class A drugs after a newspaper sting operation accused her of offering to introduce an undercover reporter to a drug supplier.
She was originally arrested on 4 June 2013.
Tulisa appeared in court today alongside rapper Mike GLC - real name Michael Coombs, who has also been charged in relation to the incident. He too has denied any wrongdoing.
