The pair were seen leaving the legendary Electric Lady Studios in New York at the same time last year, as Joe is also a musician under the alias Djo, and best known for his viral hit 'End of the Beginning', and he's revealed the 'Fortnight' hitmaker, 34, told him she is a big fan of the tune.
Speaking about the speculation they worked together, Joe, 32, told 'The Spout Podcast', he spilled: "I just happened to be there the day that she was there. And she's really nice. I mean, I've met her a couple of times.
"Before anything happened with this track, she said, 'Hey, I really love that track of yours, 'End Of Beginning.'
"She just said she had heard the song and, you know, obviously I'm like, 'What? You heard that song? How the hell did you hear that song?'"
He went on: "She's like a music lover, really. She's also so hip to new music and things that are coming out. So, I guess it's not shocking to me because she's like a big fan of music and just digs around and finds stuff.
"Somehow it came across her desk, and she listened to it and then said that she liked it. Really, really nice of her."
Addressing the hearsay that they could be collaborating, he previously told 'The Tonight Show Starring Jimmy Fallon': "Well, that was a very confusing day because I was just in there with John, minding my own business, not doing anything, and then I walked out the door, and it was like 1,000 people were standing out there.
"People looked at me expecting Taylor, and were like, 'Who's this guy?'"
