The song, which crowned the Official UK Singles chart in September, reaches the Hot 100's top 10 in its 25th week.
The song reaches the top 10 in its 25th week on the chart, marking the longest climb to the region since gnash's "I Hate U I Love U," featuring Olivia O'Brien, also ascended to the tier in its 25th week on Oct. 22, 2016.
British pop singer-songwriter Dua Lipa (that's her real name) previously charted two Hot 100 entries: "Blow Your Mind (Mwah)" (No. 72, November 2016) and "Scared to Be Lonely," with Martin Garrix (No. 76, May 2017).
"Rules" is powered most strongly by airplay, as it rises 7-4 on the Radio Songs chart (98 million in all-format audience, up 7 percent, in the tracking week ending Jan. 21, according to Nielsen Music). It also hits a new high (4-3) on the mainstream top 40-based Pop Songs airplay chart.
The track first broke internationally, becoming Lipa's first No. 1 on the Official UK Singles chart for two weeks in September.
The empowerment anthem extols the virtues of keeping an ex just that ("If you're under him, you ain't getting over him," she sings).
"Every time you achieve something, you want to go after what's next," Lipa says. "I'd like to see my own shows grow and someday be a headliner, fill up stadiums. That'd be crazy, we'll see what happens. You've got to work a lot to make it where you want to be."
Still, she admits, "I can't dance. If I try, I'll trip onstage."
