In topping the chart, Eilish has set a number of records. First, \"bad guy\" is the first song to hit No. 1 after spending a record nine weeks at No. 2. Three songs -- The Weeknd's \"Starboy,\" Justin Bieber's \"Sorry\" and OutKast's \"The Way You Move\" -- spent eight weeks in the runner-up spot before they hit No. 1.

Next, \"bad guy\" also marks the first time that a song that was formerly No. 1 on the Billboard Alternative Songs chart has gone on to top the Hot 100 since Lorde's \"Royals\" in 2013.

And this will make you feel old: Eilish, born in December 2001, is the first artist born in the 2000s to have a No. 1 hit on the Hot 100. At 17, she's also the youngest artist to rule the chart since Lorde, who was 16 when \"Royals\" hit No. 1.

Meanwhile, \"Old Town Road\" has dropped to No 3 after Shawn Mendes and Camila Cabello's \"Señorita,\" which moved up from the No. 3 spot.
