Mel B's mother Andrea Brown has taken to Twitter to share news of her daughter's 16th "clear" drug and alcohol test — asking when the abuse will stop.

Andrea tweeted an image of a letter from the 43-year-old Spice Girl's doctor, which was dated Dec. 29, 2018.

The letter read: "To whom it may concern: Melanie Brown presented in this office today for an observed instant 10-panel drug screening.

MEL B ACCUSED OF 'SOLICITING' FRIEND TO COMMIT VIOLENCE AGAINST STEPHEN BELAFONTE

"She was tested for cocaine, methamphetamines, amphetamines, THC (marijuna), PCP, benzodiazepines, barbiturates, MDMA, oxycodone, and opiates.

"It was negative for all drugs.

"She also took an instant ETG 80-hour alcohol test. It was negative.

"If there are any further questions, please feel free to contact this office."

Andrea captioned the photo: "16 weeks 16 tests all clear. When will the abuse stop?"

MEL B CLAIMS SHE WAS DRUGGED THROUGHOUT MARRIAGE TO STEPHEN BELAFONTE

She ended the tweet with a purple heart, peace sign, and rainbow emoji.

She then shared the image again, this time to include the letter's date, writing: "I missed the date off -  16 weeks 16 tests all clear of drugs alcohol #STOPDV".

#StopDV typically stands for "Stop Domestic Violence."

Earlier this year, Mel went public with allegations against her ex-husband Stephen Belafonte, claiming that he began abusing her on their wedding night in 2007.

Stephen accused the star of being a drug addict, with Mel being ordered to undergo random drug and alcohol testing as part of their bitter custody battle over their seven-year-old daughter Madison.

Mel was famously estranged from her mum and sister, Danielle, after her marriage to Stephen caused family rows.

Danielle even claimed last year that she and her family hadn't seen the singer for a decade.

Andrea always made her dislike of Stephen clear on social media.

She had so little contact with her daughter that she only found out about Madison's birth in 2011 via Twitter.

She previously said: "I only found out she was pregnant because of Twitter and I found out on Twitter that she’d had the baby too."

And on not being able to get to know her granddaughters when they were younger, Andrea added: "Half of my family is missing to me.

"Every day I pine for Mel, Phoenix and Angel."

In 2014, Andrea and Danielle took to Twitter to plead for information after Mel was rushed to hospital ahead of The X Factor final, on which she was a judge.

Mel returned to The X Factor for the last live episode days later but was not wearing her wedding ring, and viewers grew concerned after they noticed that she had marks on her body.

Mel has since revealed in her autobiography Brutally Honest that she was covered in bruises after trying to break through a door following a suicide attempt when she became desperately unhappy in her rocky marriage.
