Two months after Kendrick Lamar notched his first No. 1 album on the Billboard 200 with To Pimp a Butterfly, the rapper has landed his first No. 1 song on the Billboard Hot 100 chart -- thanks to Taylor Swift.
"Bad Blood," Swift's fourth single from her blockbuster 1989 album, moves 53-1 on this week's Hot 100 chart (dated June 6), giving the pop superstar her fourth career No. 1 single and third from her current full-length, following "Shake It Off" and "Blank Space." Because Lamar, who appears alongside Swift in the star-studded "Bad Blood" music video that premiered at the top of the 2015 Billboard Music Awards earlier this month, guests on the new single edit of the track, he is listed as the featured artist on the new No. 1 song in the country.
