Louis Tomlinson has recorded an EDM (electronic dance music) track with Steve Aoki.
The One Direction singer and the US DJ decided to collaborate after becoming friends earlier this year and the new song is expected to be released later this month.
A source told the Daily Star newspaper: "Louis and Steve partied a few times in the summer.
"They were just mucking around in the studio at first but ended up coming up with something special. It's miles away from what Louis did with One Direction."
Louis and Steve partied together in Ibiza during the summer and the 24-year-old star recently jetted to Las Vegas with pals to help celebrated Steve's 39th birthday.
It has been claimed that Louis will give the first performance of the new song during the live final of 'The X Factor' - the show which launched One Direction to fame - later this month.
News of the collaboration comes after it was recently revealed that Louis has finally decided to follow in the footsteps of his band mates - Niall Horan, Harry Styles and Liam Payne - and previous member Zayn Malik, in launching his own solo career.
And he has decided to work with Simon Cowell's Syco label, where the band are also signed.
A source recently said: "Louis is a brilliant songwriter and had not initially planned his own solo career.
"But he's been back in the studio and has been working on some really amazing music.
"He's played some to the powers-that-be at Syco, who are really excited.
"They think he could be a real success as a solo artist, given his proven ability to write hit records and massive fanbase as part of 1D."
