Grimes has come under fire after claiming that her ex-partner Elon Musk sometimes "lives below the poverty line".
Speaking to Vanity Fair, the Canadian singer spoke about her relationship with the Tesla founder and recalled moments in which Musk seemed to adopt a minimalistic way of living despite his immense wealth.
"Like, bro wouldn't even get a new mattress," the 33-year-old told the publication.
"Bro does not live like a billionaire. Bro lives at times below the poverty line," Grimes added. "To the point where I was like, can we not live in a very insecure $40,000 house? Where the neighbors, like, film us, and there's no security, and I'm eating peanut butter for eight days in a row?"
Perhaps unsurprisingly, social media users did not take too kindly to Grimes' choice of words, given that her ex-partner, CEO of SpaceX, has a net worth of over $200 billion and is the second richest person on the planet.
One person responded: "Is anyone going to break the news to Grimes that being cheap is not the same thing as being in poverty oh my God."
Another wrote: "Worst part is she doesn't know the different between being CHEAP and POOR."
A third chimed in to say: "I usually love when two weirdos get together and are weirdos together in love but I’m going to need Grimes to shut up about how Elon 'lives below' the poverty line when the dude is a billionaire and there is kids starving in every community in the 'richest' country in the world."
A fourth commented: "lol @ grimes saying elon musk lives 'below the poverty line' because he won’t get a new mattress. [How about] the people who don’t have mattresses?
"I’d love to see these billionaires live a WEEEEEK below the poverty line. please. make it a series. 30 days like morgan spurlock used to do."
Elsewhere in the interview, Grimes revealed that she and Musk had welcomed a second child, a baby girl, via surrogate in December 2021.
The baby's full name is Exa Dark Sideræl, but according to Vanity Fair, they've given her the nickname, Y.
