Billie Eilish is the latest high-profile entertainer to back Vice President Harris's White House bid, urging her fans to "vote like your life depends on it."

"We are voting for Kamala Harris and Tim Walz because they are fighting to protect our reproductive freedom, our planet and our democracy," Eilish said in a video posted on social media on Tuesday.

"We can't let extremists control our lives, our freedoms and our future," Eilish's brother and longtime collaborator, Finneas O'Connell, said in the message shared with the "Lunch" singer's more than 7 million followers on X. 

"The choice is clear," the post said.

"Vote like your life depends on it — because it does," Eilish, 22, said.

Eilish supported Joe Biden's 2020 presidential campaign and performed at that year's virtual Democratic National Convention. The performer met with Biden at the White House in 2022. 

Eilish's endorsement, which coincided with National Voter Registration Day, came on the heels of another music superstar voicing her support for Harris's campaign.

In a surprise social media announcement last week immediately following the presidential debate between Harris and former President Trump, Taylor Swift said she planned on casting a ballot for Harris in November.

Harris, Swift wrote in a lengthy Instagram post, "fights for the rights and causes I believe need a warrior to champion them."
