The 'Carry On (Her Letter To Him)' hitmaker let this one slip in an EXCLUSIVE chat, saying: "The first time I worked for her I wrote a song for her, which in itself was surreal."
"This time around I actually did a duet with her," he continued. "It's her and me on one song, which was a challenge to say the least! I was trying to figure what I was even doing there — why would they need my voice when they have hers?"
Good question. Probably because she wanted the song as a duet.
"She wanted to do the song as a duet and I was flattered, but it definitely made me question my vocal ability."
No news on when this groundbreaking 'collab' will appear though. Apols.
