The former X Factor judge shared a picture to Instagram on Wednesday afternoon (30 July) showing her getting her hair and make-up touched up.
She added the simple caption: "Back to work."
Tulisa didn't give any indication of what she was doing but recent reports have said she's been back in the studio working on new music.
Last week, a source told The Mirror: "This past week has been absolutely manic, but Tulisa just wants to get her head down now and focus on work... She is hoping to have a new single out before the end of the year."
The 26-year-old is trying to get her professional life back on track following last week's court decision to dismiss a charge against her.
Tulisa walked free from court on Friday after a judge dismissed a charge of being concerned in the supply of drugs which arose following a newspaper sting operation last year.
She had always denied the charge.
This week, she's been speaking out for the first time about her "nightmare" year and how her projects and endorsements were frozen during the court case.
Tulisa has said she's looking forward to getting back to work, adding to ITV's This Morning: "You have to look at the positives in everything and the positive for me is how much I've grown as a person - so if I'm a better person, if I have the chance to have my career back, then I can do better with my career."
