Billie Eilish attends the 2019 iHeartRadio Music Awards which broadcasted live on FOX at Microsoft Theater on March 14, 2019 in Los Angeles. 

Add Demi Lovato and Niall Horan to the growing list of famous artists who are blown away by the music of Billie Eilish.   

The 17-year-old hybrid singer-songwriter recently became the youngest-ever female artist to top the U.K. album chart with her debut album, When We All Fall Asleep, Where Do We Go? The release is also heading for a No. 1 debut on the Billboard 200 albums chart.   

In March, Foo Fighters frontman Dave Grohl gushed about Eilish and her rock star status, saying, "the same thing is happening with her that happened with Nirvana in 1991." The hard-to-categorize artist has also been praised by artists like Tove Lo, Bhad Bhabie and Jessie Reyez.

Lovato praised Eilish's song "Bad Guy" in her Instagram Story Saturday (April 6), writing, "I know everyone is posting this and that's because it deserves to be talked about by everyone but this is f---ing fire. Big fan here."    

Horan shared Lovato's enthusiasm, writing on Twitter Friday: "Currently listening to the new @billieeilish album! This woman does not f--k around. It’s so good."

Eilish will be heading out on a summer tour in support of her debut album, beginning with back-to-back weekend performances at Coachella in mid-April, followed by U.S. theater dates through July.
