Harry Styles and OneRepublic frontman Ryan Tedder have been working on new material together.
The One Direction star - whose band mates Liam Payne and Louis Tomlinson also worked with Ryan on their last album 'Midnight Memories' - has stepped into the studio with the songwriter on his own for the first time.
A source told The Sun newspaper: "Harry and Ryan have been working on new material together.
"They've met a number of times before with the band but have never worked together properly.
"There's a mutual appreciation there. If there's one person to get the best out of Harry, it's Ryan.
"The new relationship will come in handy if Harry ever try his hand at going solo."
Ryan has worked with the likes of Elle Goulding and Leona Lewis and has been back in the studio writing with Adele on material for her highly-anticipated new album, the follow-up to the chart-conquering '21'.
Meanwhile, One Direction - also formed of Zayn Malik and Niall Horan - have been working on their next record.
Liam said: "We just wanna make good music, and this album - honestly, every lad out there tonight who's thinking One Direction are this and that. Literally, next album - pick up our album and see what you feel."
