Mendes is the first male to top both tallies simultaneously with different songs.
Shawn Mendes becomes the first male artist to top Billboard's Pop Songs and Adult Pop Songs radio airplay charts simultaneously with different songs, as "Señorita," with Camila Cabello, rises to No. 1 on Pop Songs and his own "If I Can't Have You" ascends to the top of Adult Pop Songs.
Only one artist previously led both lists with different songs in the same week: On surveys dated Oct. 26, 2002, Avril Lavigne hit No. 1 on Pop Songs with "Sk8er Boi" for a single frame, while "Complicated" continued its eventual 16-week reign on Adult Pop Songs.
With "Señorita," Mendes adds his third Pop Songs No. 1, after "Stitches" (two weeks, 2015) and "There's Nothing Holdin' Me Back" (two, 2017). Cabello collects her fourth Pop Songs topper, following "Bad Things," with Machine Gun Kelly (two, 2017); "Havana," featuring Young Thug (seven, 2017-18); and her own "Never Be the Same" (two, 2018). (She also led as a member of Fifth Harmony, whose "Work From Home," featuring Ty Dolla $ign, spent two weeks at No. 1 in 2016.)
In the span dating to his first week atop Adult Pop Songs (Feb. 6, 2016, with "Stitches"), Mendes' five No. 1s are the most among all artists. Since Cabello's first frame at No. 1 on Pop Songs (Feb. 18, 2017, with "Bad Things," her four leaders tie her with Ariana Grande for the most among all acts.
"Can't" is an Island/Republic Records release (Mendes' label homes), while "Señorita" is on Island/Republic and SYCO/Epic Records (Cabello's).
The Pop Songs chart measures total weekly plays, as tabulated by Nielsen Music, among its reporting panel of 168 mainstream top 40 stations, while Adult Pop Songs reflects weekly plays on 85 adult top 40 reporters.
All charts, dated Aug. 31, will update tomorrow (Aug. 27) on Billboard.com.
