The former X Factor judge was seen heading into Westminster Magistrates Court in London with her head held high. She was wearing a black vest and jumpsuit teamed with a black blazer and a pair of Louboutin heels.
Tulisa also styled her long blonde hair extensions into big curls, no doubt the result of her last minute trip to the beauty salon on Tuesday (17 December).
The 25-year-old former N-Dubz star was spotted outside the west London salon in the evening, but opted to keep a low profile by wearing a hoodie and sunglasses.
Earlier this month, a Crown Prosecution Service spokesman confirmed that Tulisa was to be charged with being concerned in the supply of Class A drugs following an alleged incident in the summer.
She was arrested in June after it was alleged in The Sun newspaper that she had introduced a journalist to drug dealer. Tulisa's rep has indicated that she will plead not guilty to the charge.
