1 after previously peaking as high as No. 5 with both "Good For You," featuring A$AP Rocky, in 2015 and "Same Old Love" in 2016. (She adds her eighth top 10 and first since "It Ain't Me," with Kygo, reached No. 10 in May 2017.)

With Gomez having first appeared on the Hot 100 dated Jan. 10, 2009 (at No. 99 with the eventual No. 58-peaking "Tell Me Something I Don't Know"), she reaches No. 1 at last, 10 years and 10 months after her first entry. She completes the longest wait from a first visit to a first No. 1 (as a lead artist) since Daddy Yankee, who took 12 years and nine months from his first charted title to his first leader, "Despacito," with Luis Fonsi andfeaturing Justin Bieber, in May 2017.

Among women, Gomez ends the longest wait for a first Hot 100 No. 1 in over 30 years, since pop icon Bette Midler needed 16 years, six months and two weeks from her first appearance in 1972 to her first No. 1, "Wind Beneath My Wings," in June 1989.

(Among all artists, Santana holds the mark for most time between a first Hot 100 visit and first No. 1: two days shy of 30 years until "Smooth," featuring Rob Thomas, reached the top spot in October 1999.)

Reigning producers & writers: "Lose" was produced by the team of Mattman & Robin (Mattias Larsson and Robin Frediksson), who wrote it with Gomez, Julia Michaels and Justin Tranter.
