Sam Smith has revealed that they are "100%" certain they had coronavirus last month and passed it on to their sister.
The 27-year-old 'Money On My Mind' singer isolated for three weeks after displaying symptoms of COVID-19, which has killed more than 150,000 people worldwide to date.
"I didn't get tested but I know I have it, 100% have it," Smith told Zane Lowe's Apple Music show. "I'm just going to assume that I did because everything I've read completely pointed to that.
"So yeah, I think I definitely had it. And then as soon as I had it, my sister five days after me started getting the same symptoms who's living with me.
"So me and her just isolate for three weeks because we knew. It was clear. Because I've got an older nan and stuff, so we didn't want to risk anything. I got it about two weeks before the UK really hit.
"Well, I think I got it. I don't 100% know, but I got it and then as everyone was kind of really on lock down, that's when I got over it, luckily."
Smith recently announced that they had decided to postpone the release of their new album and change its title from To Die For in light of the pandemic.
