The 18-year-old Canadian singer and 23-year-old One Direction star have been rumoured to be getting together to write a song for months, and now the 'Treat You Better' hitmaker has met with the Irish hunk and they have talked about working on a song when their schedules align.
Asked if the collaboration is happening, Shawn told Roman Kemp on Capital FM: ''Yes, definitely, it will. Eventually when we get time. I met him for the first time the other day, but it's funny because we felt like we knew each other because we were talking back and forth for a long time. But yeah, when we get the chance, I'd love to write with him. I think he's incredible. He's got this great, great vibe happening with this whole acoustic thing so I think I really want to get involved with it, if he is down. Which he is, I think.''
The pair met at the 2016 BBC Teen Awards last weekend where Niall performed his first ever solo gig.
And Shawn was named Best International Solo Artist and his song 'Stitches' was crowned Best Single at the star-studded ceremony in London.
delighted the audience at the SSE Wembley Arena in London when he surprised the crowd by kicking off the event with a performance of his debut solo song 'This Town'.
However, the sound cut during his performance but the 10,000-strong audience helped out by singing along and Niall insisted he didn't feel strange going it alone.
Asked by co-host Nick Grimshaw if he felt lonely without the rest of the group, he said ''definitely not''.
He added: ''It's hard to feel lonely with 10,000 people in front of you.''
