Sorry, "Old Town Road" fans: A new song has finally climbed to the top of the charts.
Billboard tweeted that the 17-year-old Eilish, whose song was No. 2 for nine weeks, "is the first artist born in the 2000s to have a No. 1 song on the #Hot100."
Lil Nas X, whose real name is Montero Lamar Hill, took to Twitter to congratulate Eilish.
"U deserve this!!" he wrote.
Cyrus echoed the sentiment.
"Well deserved," he tweeted. "Your persistence paid off. Thanks everybody. It was a hell of a ride."
