Calvin Harris must have one hell of a 'Contacts' list in his phone.

The Scottish DJ and producer is knocking out collaborations with big names left, right and centre - and the latest, following his recent track with Migos and Frank Ocean, is one of his most star-studded yet.

'Heatstroke' features rapper Young Thug, Pharrell and Ariana Grande, no less, and was teased by the EDM maestro on Twitter.

There's no release date as yet, but considering he doesn't like to hang around, you can expect to hear it sooner, rather than later.
