Duos are ruling the roost on this week's Billboard Hot 100 in the United States, with two occupying the highest positions and a collaboration breaking into the Top 10 for the first time.
The latter comes from Charlie Puth and Selena Gomez, who rise from 12 to Number 10 with We Don't Talk Anymore. The duet marks Charlie's second US Top 10 single following his Number 1 See You Again with Wiz Khalifa. Selena notches up the sixth Top 10 of her career, and first as a featured artist.
At the top of the chart, a fourth consecutive week at Number 1 is the reality for The Chainsmokers and their track Closer featuring Halsey. Just behind them are the ascending twenty one pilots, who hop one place from 3 to 2 with Heathens. This matches their personal best slot previously hit by their single Stressed Out.
With duos reigning supreme, this marks the first time in over 31 years that a pair of duos have held the Number 1 and 2 positions, and only the fourth occurrence in history. The most recent instance was back in May 1985, when Tears for Fears' Everyone Wants To Rule The World held Wham!'s Everything She Wants off the top spot.
Further down the chart, Adele's Send My Love marches three places to a new peak of Number 8 while Ariana Grande's Side To Side ascends 15 places to Number 18.
Over on the Billboard 200 albums chart, Travis Scott betters his UK placing of Number 19 to score his first US Number 1 album with Birds in the Trap Sing McKnight. 88,000 combined units was enough to secure the top spot ahead of A Day To Remember, although ADTR's Bad Vibrations was the biggest seller of the week.
