The move comes just two days after she announced her engagement to her lifelong boyfriend Sam Asghari.
CNN has contacted Spears representatives to comment.
A source close to the singer says that “it was her decision” to delete the account and that it has been something she “wanted to do for a while”.
The Grammy winner is two weeks away from a court hearing that could determine whether or not she stays at her court-ordered conservatory. Spears has been in a parole conservatory supervised by his father, Jamie Spears, for 13 years.
Earlier this month, her father filed a petition to end the conservatory citing her daughter’s two emotional testimonies during the summer in which she said she wanted to return to her freedom.
He also said he wanted to accuse his father of conservative abuse.
Meanwhile, Spears’ recently hired lawyer, Mathew Rosengart, has filed several petitions in an effort to pressure his father to stop acting as the custodian of his $ 60 million property.
The next court hearing is scheduled for Sept. 29.
