The song also earns Beyonce a spot in an exclusive Billboard Hot 100 club - she is among only 21 acts who have scored seven or more number ones. She also ties Mariah Carey as the only artist to have landed chart-toppers in each of the last three decades.
Megan and Beyonce's success continues a run of number ones for artists and guests, which began with Travis Scott (II) and Kid Cudi's "The Scotts", which debuted at the top on 9 May. Doja Cat's collaboration with Nicki Minaj also hit the summit a week later, before they were replaced by Grande and Bieber.
Doja Cat's "Say So" holds at two on the new chart, while The Weeknd's "Blinding Lights" rebounds from four to three, DaBaby's "Rockstar", featuring Roddy Ricch, is at four, and Drake's "Toosie Slide" rises a spot to round out the top five.
The remainder of the top 10 is: "Life is Good" by Future, featuring Drake, Roddy Ricch's "The Box", Dua Lipa's "Don't Start Now", "Intentions" by Justin Bieber, and Post Malone's "Circles", which extends its top 10-run record to 38 weeks.
