Ne-Yo has spoken out after walking off-stage during a concert Thursday, femalefirst.co.uk reports.

The singer told fans he wasn’t feeling well at the start of his Manchester show. Fans watched as the sweat-drenched star struggled to move and propped himself up on a table before exiting the stage for a break.

A tearful Ne-Yo then reappeared, telling the audience, “I’ve never not completed a show, I’ve never done this before.”

On his blog, Ne-Yo explained: “I have an issue with not knowing when to say enough is enough, so last night in Manchester, my body said it for me.

“For the last five days I’ve been dealing with a sinus infection. I paid it no real mind, and kept on going, like I always do. My voice couldn’t take it.”
