As well as being one of the most unique pop stars on the planet, Grimes is a really kooky character when it comes to just about everything in life - including workout routines.
If you remember, last year actor Mark Wahlberg was widely mocked for sharing his daily workout, which included waking up at 2.30am, a session inside a cryo chamber and a round of golf.
Well, his routine looks like child's play compared to what Grimes apparently puts herself through every day, which includes hiking, sword fighting, a screaming session and removing the 'top film of her eyeball' thanks to 'experimental surgery', which helps her avoid seasonal depression.
She revealed all this on a now-viral Instagram post that appears to have been an advert for Adidas and Stella McCartney, which has to be read to be believed.
The post, which could or could not be true (it definitely isn't true...is it?) has since become a meme and people can't stop making jokes about it.
