#NewMusicFriday just got even bigger.
Arriving August 17, Promises will feature Sam Smith. This first-time collaboration follows the world's highest-earning DJ's longest-reigning Number 1 ever One Kiss with Dua Lipa, which spent eight weeks at the top of the Official Singles Chart.
Calvin was first to announce the news (see above) with Sam adding: "Surprise!!!! I’m so excited for you all to hear this song."
Calvin will be looking to enter double figures and claim his 10th Official UK Number 1 single, while Sam may bag himself a seventh chart-topper, should/when Promises be a monster hit.
Calvin Harris also ties the record for the most Number 1 hits this decade with Jess Glynne and Tinie Tempah, with all three artists scoring seven Number 1s since 2010. View Calvin Harris' full UK chart history here, and take a look back at Sam Smith's hits back catalogue.
