Billie Eilish took to Instagram on Thursday to express her strong disapproval of Elon Musk’s billionaire status, using some colorful language to make her point.

The 23-year-old singer of “Bad Guy” shared a series of Instagram Story slides suggesting ways the 54-year-old tech mogul could put his wealth to better use, such as tackling global hunger and safeguarding endangered species.

In a follow-up post, Eilish didn’t hold back, referring to Musk with an expletive-laden critique, calling him a “f–king pathetic p—y bitch coward.”

Elon Musk, the founder of Tesla, made headlines last month when Forbes reported he became the first individual to reach a net worth of $500 billion.

The content Eilish reposted, originally from My Voice My Choice Org, speculated about Musk’s potential impact on critical global issues. It suggested that with a $40 billion annual donation, Musk could potentially eradicate world hunger by 2030, or with $1-2 billion each year, he could help preserve over 10,000 critically endangered species.

Additionally, the organization hypothesized that Musk could rebuild Gaza for $53.2 billion.

A rep for Musk did not immediately respond to Page Six’s request for comment.

Musk is only the latest billionaire Eilish has called out in recent weeks.

The Grammy winner made headlines in October for putting billionaire tech founder Mark Zuckerberg on blast during her acceptance speech at the WSJ. Magazine Innovator Awards.

The 23-year-old called out wealthy elites at the event — which was attended by power players including Hailey Bieber, George Lucas and Karlie Kloss — as she questioned billionaires not giving away their exorbitant funds.

“We’re in a time right now where the world is really, really bad and really dark and people need empathy and help more than, kind of, ever, especially in our country,” Eilish said at the time, adding that those who “have money” should “maybe give it to some people that need it.”

She continued, “Love you all, but there’s a few people in here that have a lot more money than me. If you’re a billionaire, why are you a billionaire? No hate, but yeah, give your money away, shorties.”

Many audience members laughed and clapped at Eilish’s suggestion — but Zuckerberg did not, one source told People.

The songwriter, meanwhile, made sure to put her money where her mouth is.

At the ceremony, Stephen Colbert announced that Eilish donated $11.5 million from her “Hit Me Hard and Soft” tour proceeds toward “organizations, projects and voices dedicated to food equity, climate justice, reducing carbon pollution and combating the climate crisis.”
