Musk has been 'very immature' on Twitter, says Grimes

Elon Musk's girlfriend Claire Elise Boucher, better known as Grimes, has admitted that the tech baron has been 'very immature on Twitter'.

Over the weekend, the 33-year-old posted a TikTok video of her dancing with swords to 'Save Your Tears' remix featuring Ariana Grande.

A user asked the musician to confirm that her boyfriend is not a "men's rights activist", to which she replied that her 49-year-old boyfriend is certainly not one but has definitely been very immature at points on Twitter.
