“Bad Guy” made Billie Eilish the first artist born in the 2000s to top the Billboard Hot 100.
Eilish was born on December 18, 2001, and released “Bad Guy” in 2019 as the lead single from her debut studio album, When We All Fall Asleep, Where Do We Go? The minimalist pop track was written by Eilish and her brother Finneas, who also produced it.
The song initially entered the chart below the summit, then rose to No. 1 after a remix featuring Justin Bieber. It reached the top in August 2019, replacing Lil Nas X’s “Old Town Road” after that song’s record-breaking run.
The milestone is about the performer’s birth year, not the song’s release year. Eilish was also a teenager when the song became a chart-topper. “Bad Guy” helped define her unconventional early sound and became her first U.S. No. 1 single.
