Niall Horan teamed up with the songwriter that helped Adele to pen her hit single When We Were Young for his new single Slow Hands.
While taking part in a Twitter Q&A session with his fans, former One Direction singer Horan was asked who he worked with on his second solo single.
"Julian Bunetta. I also wrote it with Tobias Jesso Jr, who I guess is most famous for writing When We Were Young with Adele," Horan tweeted. "He's a great guy too, so we're happy with how things are going."
Horan made his solo debut last year with This Town, a laid back love song, and Slow Hands sees him go in a similarly acoustic but more uptempto direction.
Last week the Mullingar man told Nick Grimshaw on BBC Radio 1 that it was a "nerve-racking time" around the single's release, adding: "I wrote this song a few months ago so I've been waiting for people to hear it."
He said the track had been inspired by music styles from the 1980s.

After recording it in Los Angeles, he said: "I've been listening to a lot of early 80s stuff lately and been inspired by that heavy bass and the funky guitar sound.
"It's another flavour to my album that I'm excited to share."
Horan has been teasing fans with hints about progress on his upcoming solo record throughout the year, but no release date has been officially set.
