It seems that Eilish didn't intend on discussing the syndrome until a change in lighting prompted one of her tics.
“If you film me for long enough, you’re going to see lots of tics,” Eilish admitted to the legendary talk show host. “I don’t care. It’s really weird, I haven’t talked about it at all. The most common way people react is they laugh, because they think that I’m trying to be funny. They think I’m [ticcing] as, like, a funny move… And I’m always left incredibly offended by that.”
She added that she's far from the only celebrity to have Tourette’s and that many are not open about it.
Eilish continued: “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 want to talk about it, but that was really interesting to me. I was like, ‘You do?! What?’”
“These are things you would never notice if you’re just having a conversation with me, but for me, they’re very exhausting,” she explained. “It’s not like I like it, but it’s part of me. I have made friends with it. And so now, I’m pretty confident in it.”
