Pharrell Williams persuaded Calvin Harris to sing on his new single 'My Way'.
The 43-year-old 'Happy' hitmaker convinced the superstar Scottish producer to sing lead vocals on the track - making it the first song the hunky DJ has sung on since 2014's 'Summer'.
Speaking to Zane Lowe on Apple Music's Beats 1, Calvin said: "[There's] only so far you can go with a voice like mine, and there's a limit to the range. Actually, Pharrell told me something about hitting the notes. Occasionally people try to persuade me to sing again and he was one of those people."
Calvin, 32, who split from girlfriend Taylor Swift earlier this year, also revealed that Pharrell's advice and vocal praise encouraged him to try different things.
He said: "It's not about hitting the notes, it's about getting the emotion and the feeling and the character across. Once he said that to me, I started looking at myself [and] my voice differently 'cause I was like, 'Hmm, someone like him picked up on that.'"
The 'Outside' hitmaker has previously passed on the lead vocal duties to pop singers including Ellie Goulding and Rihanna, but Calvin has admitted he's keen to keep recording his voice for his songs.
He added: "Yeah, I'm trying to work hard to do it more. Because also, in tandem with that, there's a lot of DJ producers, and I look at myself and I think, 'What do I have to offer that they don't? What can I do that they can't?' "Because you know, we all pretty much do the same thing."
