Payne and Smith have broken up after dating for over two years, reports eonline.com.
No details on what caused the split have yet been revealed.
The pair began dating in May 2013, but met much earlier when they were students in Wolverhampton when they were younger.
While the 22-year-old singer hasn’t publicly addressed his breakup, he did tweet something on Friday that may have hinted that there was trouble in paradise.
“I love how music is always there for you when you need it most x,” he wrote.
