The N-Dubz star was pictured arriving at Chelmsford Magistrates Court in Essex this morning (2 July) and was smartly dressed in an all-black outfit with cream jacket.
Tulisa, who had plaited her long brunette hair, kept her eyes covered with a pair of dark sunglasses and looked serious as she made her way inside.
Former X Factor judge Tulisa is accused of attacking blogger and new TOWIE star Vas (real name Savvas) Morgan at V Festival last year.
Vas has claimed that he was left with swelling to the eye, however Tulisa denies the assault charge and insists Vas had a "strange obsession" with her.
Last month, Tulisa's court case was adjourned after two days, as the district judge wanted further witnesses to be called.
At the time, Tulisa had also told the court that she believes Vas had a "vendetta" against her after she apparently asked security to remove him from a London nightclub.
Tulisa's PA, Gareth Varey, also stands accused of threatening behaviour, which he denies.
The trial continues.
