17-year-old star Billie Eilish recently appeared on Ellen DeGeneres’ show and pranked by a fake Justin Bieber.

She also performed her famous song, “When The Party s Over” when the Foo Fighter singer Dave Grohl was in the audience to support her.

Dave Grohl once had an interview with Variety, and compared Eilish with Nirvana in the ’90s:

“My daughters are obsessed with Billie Eilish. The same thing is happening with her that happened with Nirvana in 1991. People say, ‘Is rock dead?’ When I look at someone like Billie Eilish, rock and roll is not close to dead!”
