From Zayn Malik to Justin Timberlake, see the former boy-banders who've hit the No. 1 spot on the Billboard 100 and 200 charts.
Zayn was no stranger to the No. 1 slot on the Billboard 200 albums chart as part of One Direction — the group claimed four chart-toppers on the list between 2012 and 2014. Zayn departed the act in early 2015, and saw his solo debut single “Pillowtalk” and his first album, Mind of Mine, open at No. 1 on the Billboard Hot 100 and Billboard 200, respectively, in 2016.
