The former X Factor judge was arrested in June after it was claimed in The Sun that she introduced a journalist to a drug dealer.
In a statement today (9 December), Baljit Ubhey from the Crown Prosecution Service said: "We have determined that there is sufficient evidence for a realistic prospect of conviction."
Ben Rose, speaking on behalf of Tulisa, gave a statement to the BBC, indicating that she would be pleading not guilty.
He added: "In due course Tulisa will give a full answer to these allegations in court."
Tulisa was employed as a judge on The X Factor from 2011 to 2012.
The Metropolitan Police Service (MPS) has also charged Michael Coombs with supply of class A drugs.
