Brian Harvey denied he was on “cocaine” after clashing with his ex Danniella Westbrook.
They dated when the former EastEnders star was just 21.
Now the exes, who romanced from 1991 until 1995, have gone to war over social media 26 years after their relationship ended.
In a furious tirade, Brian hit back at his ex Daniella for claiming he was on “coke” after he called her a murderer and a paedophile.
He said in a piece to camera: “I’m fed up with your lies and your cover ups. And talking me up like I love him, I care.
"He’s a c***, he’s on coke. I ain’t on coke. I’m offering you the chance to prove to this country you aren’t on coke and I’ll do exactly the same.”
The singer, who was sacked from band East 17 for claiming ecstasy was a "safe" drug, said he hadn’t seen Danniella in 15 years.
He went on: “I haven’t seen her for 15 years or whatever it is.”
It comes after Danniella accused Brian of being a “paranoid coke freak” - which the singer vehemently denies.
In an Instagram live, she told the cameras: ”You are a paranoid coke freak which I used to be, where you think everyone at your front door is MI5 and they're gonna come through your door. They ain’t mate.
"It's people like you that put me back into relapses. But you're not going to do that. He thinks I've got convictions. He's on there saying I brought MI5 to his house and stuff like that. What am I, Ms Money Penny?
"You're fully live on your YouTube crying, sobbing, slandering me saying I am involved in paedophile rings. Mate I was abused all my life in this industry, you wasn't Brian. You're one of the lucky ones son, so why you're sitting locked in your f***ing house with bars on your windows I don't know."
She said: ”I’m fuming with him. What a d**k head. I'm just going to address Brian Harvey slandering the s**t out of me. Saying I'm a murderer, stuff like that. Saying I set him up with a paedophile ring. Calling me a groomer. He's mad...
"The geezer's live on YouTube moaning, calling me a paedophile. I'm furious with him because he's slandering my name.”
Setting the record straight, Danniella said she was trying to put her past and addiction behind her.
The actress shared her emotional outburst with her 20.1k followers on Instagram.
She said: ”I’m just a woman who is trying to do the right thing and putting her past behind her and addiction behind her.”
