The former X Factor judge shared a photo to Instagram on Friday afternoon showing herself working away in a recording booth.
Her caption simply said: "Studio."
Tulisa's made no secret of her desire to get back to work following a difficult twelve months that saw her being targeted by a newspaper sting operation and charged with being concerned in the supply of drugs – a charge she vehemently denied.
After a yearlong ordeal, she walked free from court last week after a judge dismissed the case.
In a statement outside court, Tulisa said: "Let me be perfectly clear. I have never dealt drugs and never been involved in taking or dealing cocaine. This whole case was a horrific and disgusting entrapment."
"I have not been able to work for a year, and I am now looking forward to resuming my career," she added. "I will use these experiences to make me stronger. I would like to thank all the people who have supported me through this terrible ordeal, including my fans and, of course, my legal team."
Since then, the N-Dubz star has been speaking out about getting her life back on track, and her desire to get back to doing what she does best: her music.
And fans are clearly happy with comments on her Instagram post including, "The Female Boss is back!" and "This is where you belong." Another poster said: "So glad you're okay and you're back. Singing and writing songs will cheer you up Muffin. Have fun!"
Last week, an insider 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."
Tulisa herself told 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."
