Tulisa, 26, had been charged with being concerned with the supply of Class A drugs, but was cleared on Monday.
Now she's back in the studio for the first time in 14 months, and it's been reported that her new music will reflect her hellish year.

A source told the Mirror: "Tulisa isn't shy about speaking her mind and a lot of her songs will detail the hell she's been through over the past 12 months.
"She won't be pulling any punches and some of it could be pretty dark and twisty."
Tulisa is reportedly desperate to get some new music out there as she was unable to work while the court case was happening.

The source continued: “She has a career to re-launch and she needs to start making some money.
“Her record label has stuck by her throughout all of this, so she wants to repay them by laying down the new tracks as quickly as possible.
She is hoping to have a new single out by the end of the year.”

Tulisa was accused of brokering a cocaine deal for undercover reporter Mahzer Mahmood, who was posing as a Bollywood film producer offering her a big money deal.
However the case was ‘thrown out of court’ on Monday after the judge accused Mahmood of lying.
Last night Tulisa attended a screening of her upcoming documentary detailing the events of the last year, set to be aired on BBC3.
