The article included an in-depth account from 26-year-old conservative influencer Ashley St. Clair, who claims Musk bought her silence after she gave birth to a baby supposedly belonging to him back in February.

Musk, within hours, was bashing the Journal - touting it as worse than TMZ.

'TMZ >> WSJ,' the billionaire wrote. 

It wasn't his first time panning the paper, which he branded as 'trash' back in January. The barb came in direct response to a separate report surrounding his alleged pervasive drug use and concerns it was causing his companies' directors.

The Wednesday report alleged the billionaire is building a massive brood ahead of a prospective population collapse - a clandestine campaign now creating 'harem drama'.  

On paper, Musk has fathered at least 14 children by four women - but the Journal report suggests the true number is much higher.   

Armed with a paternity test said to be '99.9999 percent' accurate, St. Clair claimed Musk allegedly offered her $15million and $100,000 a month to not disclose he is the father of her child - an arrangement she says is in place with several other women.

She said Musk strategically recruits 'candidates' like her through X - before hitting them with NDAs. 

'The Tactics Elon Musk Uses to Manage His 'Legion' of Babies - and Their Mothers,' the WSJ piece's headline blasted, bolstered by a portrait style photo of St. Clair and her son, Romulus.

'The world's richest man juggles more than a dozen children and 'harem drama' along with running his companies and advising Trump,' a subhead insisted as well.

'[Musk] recently took a paternity test in a battle with one woman over money and privacy.'

The report them jumps directly into St. Clair's perspective, and her  efforts to get Musk, 53, to take a paternity test before giving birth.

That put her into contact with Musk's fixer, Jared Birchall, whom fielded her concerns during  a two-hour phone call that took place in December, according to the Journal.
