Elon Musk hits back at Billie Eilish with savage 8-word remark after singer blasts his near trillionaire status

Billie Eilish and Elon Musk have been feuding online over the SpaceX founder's pending trillionaire status.

Earlier this month, Musk and the Tesla board agreed the largest corporate pay package in history, which will see Musk become the world's first trillionaire should he meet a series of targets over the next 10 years.

Some of the targets include delivering 20 million Teslas in this time frame, as well as roll out one million self-driving Robo-taxis into commercial operation.

The time of the agreement coincides with 'BIRDS OF A FEATHER' hitmaker Eilish calling out the world's billionaires to donate their money to charitable causes.

Speaking at the Wall Street Journal's 2025 Innovator Awards, 23-year-old Eilish told the crowd: "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."

"If you have money, it would be great to use it for good things and maybe give it to some people that need it," she went on, adding: "I love you all, but there's a few people in here that have a lot more money than me and if you're a billionaire, why are you a billionaire?"

Eilish, who Forbes reports has a net worth of $53 million, has since called out Musk specifically amid the news of his trillion-dollar deal and branded him a 'f**king pathetic p**sy b***h coward'.

Now Musk has reacted and he had just as unfavorable things to say about Eilish.

"She’s not the sharpest tool in the shed," he said of the singer on Twitter.

Some of Eilish's fans wasted no time in coming to her defense, however. One said: "If that’s how he talks about a Grammy-winning artist, I can’t imagine what he thinks of the rest of us. Maybe it’s time he put the tools down and started listening instead of throwing shade."

A second penned: "You notice how he knows about these world issues he can help with, and he still chooses not to do anything. Oh Billie, you’ll always be right."

"Calling Billie names doesn’t change anything. She raised a valid question about billionaires and responsibility," added somebody else.

Another fumed: "Calling someone dumb for legitimately criticizing you is some elementary school sh*t."

But others argued that celebs like Eilish shouldn't be telling others how to spend their hard-earned cash.

"His money, his choice," one Twitter user argued.

Another asked: "Why do y'all like telling rich people how to spend the money they f**king worked for."

UNILAD has approached Eilish's rep for comment.
