The grime superstar and the 'September Song' hitmaker have teamed up on the track 'Momma's Prayer' and JP has revealed the 'Big For Your Boots' rapper has a soft soulful tone to his vocals.
He told the Daily Star newspaper: ''It shows Stormzy's softer side.
''He has a lovely tone for his voice - he has a really honest delivery, in a similar way a lot of rappers do a little bit of singing in the chorus, he does on this track.''
JP - whose real name is John Paul Cooper - previously revealed the single exclusively to BANG Showbiz.
He said: ''The funny thing is there were a few plans to collaborate on a song. And a lot of people said we've collaborated on a song but it never actually happened.
''So we have written a track together and I guess people will know about it very soon and that is all I am going to say.''
Stormzy is in big demand for collaborations as Clean Bandit cellist Grace Chatto recently revealed the 'Symphony' hitmakers are hoping to get the 24-year-old star on one of their tracks.
Over the years the electronic music group - which includes also includes Jack and Luke Patterson - have collaborated with a number of artists such as Jess Glynne, Zara Larsson and Sean Paul, but the 31-year-old beauty says Stormzy is high up on their wish list.
She said: ''Yeah it would be great to do something with Stormzy.
''We've kind of spoken about it a bit and he seemed up for it at the time. So I'm hoping we can find a time to get together in the studio. Yeah, he is amazing.''
