Santa Claus failed to gift the pair a No1 when they were roped into doing Every Day Is A Holiday for H&M last Christmas.
So the DJ plans to take KP in another direction.
Chart-topper Duke, 33, told me: “With Katy the job was to do a track for a campaign.
“I spent a week with her in her studio working on that. But it never got released as a single.”
He added: “I 100% would love to get back in the studio with her for a single.”
“I think she could switch things up a little more, push the boat out a little more for the next record. Who knows what we could do?”
