The 'My Way' hitmaker shared a teaser of the artwork for new song 'Heatstroke', which features a sunset, on his Twitter account on Tuesday evening (28.03.17).
He simply captioned the post: ''CALVIN HARRIS // YOUNG THUG // PHARRELL // ARIANA GRANDE (sic)''
He also shared the credits for the song, which has been co-written by himself, Jefferey Williams and Brittany Hazzard - who is better known as Starrah - and co-wrote Rihanna's hit 'Needed Me'.
It follows his single 'Slide' with Frank Ocean and Migos.
The announcement comes a day after the 33-year-old Scottish hunk's close pal DJ Alesso, 25, said Calvin has gone ''funk'' on his new tunes.
The 'Falling' hitmaker heard some demos of Calvin's recently and called for fellow dance acts to stop following the likes of Major Lazor and be ''brave'' and come up with some ''fresh'' sounds like Calvin.
Alesso - whose real name is Alessandro Lindblad - said: ''Calvin knows we need fresh stuff.
''I saw him a couple of weeks ago in LA. He played some of his new songs they were amazing.
''He's not letting anyone put him in the corner.
''Right now, people need to be brave and stop following the trends. All the demos I'm getting sound like Major Lazor or Kygo.
''He's still doing dance but he has a lot of old school disco/funk going on. there's no drop in his songs, which is brave.''
Calvin is said to have an albums worth of new material, but fans might have to wait to hear each single bit by bit as it was previously reported he's retiring from making records.
A music insider revealed in September: ''Calvin has always been a forward-thinker and believes just releasing singles is the way forward.
Albums don't sell how they used to and artists are now seeing streaming as the future.
''Albums are time-consuming and limit artists to cycles rather than having a persistent presence in the charts.
''Calvin is one of the most-streamed artists in the world so it would make sense to exploit that success.''
