The One Direction star surprised his fans by unveiling the track on Thursday (29.09.16) on his Twitter account and making it available to listen to on all major streaming platforms, iTunes and Apple Music and music video hosting website VEVO.

His tweet read: "Been workin in the studio, wanted to share this song I just wrote with u guys. thank you for always being there (sic)"

In a statement he confirmed he has signed to Capitol Records and told the Directioners he was "looking forward to the next part of this journey together".

He said: "I'm excited to announce I have signed a record deal with Capitol Records USA and released my first solo song.

"Thank you to all the One Direction fans for your love and support as always. I'm looking forward to the next part of this journey together."

In the accompanying black and white video Niall gives a stripped-down performance of 'This Town' in a "1 Mic 1 Take" promo that premiered today on VEVO.

The clip, which was filmed in the historic Capitol Studios in Hollywood, CA, simply shows the pop heartthrob singing whilst playing an acoustic guitar.

Niall, 23, recorded the song with Adele's producer Greg Kurstin and he co-wrote the track with long-time One Direction collaborators Jamie Scott, Mike Needle and Daniel Bryer.

Fans first got an indication the 1D hunk had completed his first single when a tweet was sent from the official Radio Disney Twitter account announcing the title before being swiftly deleted.
