Back in March, it was reported that Elon was in an ‘on-off’ relationship with Australian actress Natasha Bassett, 27, after meeting on the Los Angeles social scene.
Confidential reported that the pair, who were spotted disembarking Elon’s private jet after his plane touched down in Los Angeles in February, have known one another for some time.
‘Elon and Natasha have been in an on-again, off-again relationship for a few years,’ an alleged source told Confidential.
‘I think their relationship is quite tumultuous, especially with him having the same sort of on-again, off-again type of relationship with Grimes.’

In May, Elon and Natasha were spotted enjoying a meal at the Cheval Blanc hotel in St Tropez, where rooms cost upwards of $1,300-a-night.
And at the time, it appeared she had been well and truly embraced by Elon’s family, attending multiple events in Cannes where his model mother Maye was also a guest.
The pair ate thought to have attended the premiere of Bassett’s new film, Elvis. She plays one of the singer’s girlfriends in the biopic.
The actress moved to the US from Australia when she was 19. She first worked in New York then traveled to L.A. It’s unclear how she and Musk met.

Earlier this month, Elon tweeted: ‘Doing my best to help the underpopulation crisis,’ he intoned. ‘A collapsing birth rate is the biggest danger civilisation faces by far.’
He added: ‘I hope you have big families and congrats to those who already do!’
His tweet came as it emerged that, last November, he quietly welcomed twins with Shivon Zilis, 36, a senior executive at one of his companies.
Furthermore, they arrived just a few weeks before Musk had a second child via surrogate with his on-off girlfriend Claire Boucher, alias Canadian pop star Grimes.

Musk’s two children with Grimes are two-year-old son X Æ A-Xii (pronounced ‘X-Ash-A-12’) and seven-month-old Exa Dark Sideræl. They are known as X and Y for short.
The Tesla mogul also has five children with his first wife, Canadian author Justine Musk.
A sixth child, their first, died of sudden infant death syndrome aged ten weeks in 2002, prompting them to use in vitro fertilisation. Then Justine gave birth to twins — Vivian and Griffin — in 2004, followed by triplets — Kai, Saxon and Damian — in 2006.
