Billie Eilish discussed her Tourette’s syndrome, claiming she enjoys answering inquiries about the ‘exhausting’ disease because it’s ‘interesting.’

The singer stated she feels irritated when people joke about her condition in an interview with David Letterman for his Netflix series My Next Guest Needs No Introduction.

Letterman questioned if she had spotted a fly after the Lovely singer turned her head and opened her mouth during the talk.

The 20-year-old singer said, “No, I’m ticcing,” to which the host apologised.

Eilish revealed that lights had triggered her tics, adding, “If you film me for long enough, you’re going to see lots of tics. I don’t care. It’s really weird, I haven’t talked about it at all.”

“I really love answering questions about it, because it’s very very interesting. And I am incredibly confused by it. I don’t get it,” she admitted.

The singer continued: “For me, they’re very exhausting. It’s not like I like it, but I feel like it is part of me. I have made friends with it. And so now, I’m pretty confident in it.”

Eilish, who was diagnosed with the syndrome at the age of 11, has expressed her displeasure with those who believe she is trying to be amusing when she has a tic.

“The most common way people react is they laugh, (think) that I’m trying to be funny. And I’m always left incredibly offended by that,” the singer said.

Eilish went on to say that there are other musicians in the industry that suffer from Tourette Syndrome, but she won’t name them.

“What’s funny is so many people have it that you would never know. A couple artists came forward and said, ‘I’ve actually always had Tourette’s,’ and I’m not gonna out them because they don’t wanna talk about it, but that was actually really interesting to me.”
