“Yes, I wrote a song with Harry,” she told host Nick Grimshaw, Styles’s BFF. “It was unbelievable. He’s a very, very talented songwriter – I was very impressed.”
Trainor had also revealed her collaboration to the U.K.’s Sun earlier on Tuesday, telling the outlet more specifically that the pair had written a “cute acoustic love thing” on her ukelele.
“We even recorded a rough demo together with our vocals,” she said, though it’s unlikely the rough cut will ever see the light of day given Styles’s commitment to 1D.
“I was worried he’d just be a 20-year-old boy, so I walked in with a prepared voice and chorus. But he gave me very poetic, mature lyrics,” she continued telling The Sun. “I was like, ‘Well, damn, Harry, you know what love is.’ ”
With a quote like that, we can only imagine the kind of focused determination with which Directioners will be examining the lyrics of the finished song for clues as to which “love” Styles may be writing about.
This isn’t the first time that Styles has shown off his songwriting chops. Not only does he frequently write for One Direction – though bandmates Liam Payne and Louis Tomlinson do the lion’s share of writing for the boy band – but he also wrote a song for Alex & Sierra called “I Love You” with producer Johan Carlsson.
Having only just released her full-length debut album, Title, on Jan. 13, we may not even hear the single with just Trainor’s vocals for a while yet.
