Billie Eilish has previously discussed living with Tourette's Syndrome, but this time it briefly derailed an interview before leading to a super honest conversation about the condition.
Appearing on David Letterman's Netflix show My Next Guest Needs No Introduction, Billie discussed everything from her musical influences to dealing with imposter syndrome.
At one moment mid-interview, Eilish is seen suddenly turning her head and opening her mouth, to which Letterman asks, "What's going on? The fly?" thinking that Billie was simply responding to a fly in the room.
She responds, "No I'm ticcing - the lights brought it on."
Letterman then asks if Billie is comfortable discussing it, and the two divert to a conversation on Eilish's diagnosis and how it has impacted her life.
"They think I'm going like [imitates tic] as a funny move, and so they go, 'Ha'. And I'm always left incredibly offended by that.
Letterman then realised he had responded in kind of the same way, and was worried he might have pissed her off.
"Not at all," Eilish replied, adding: "I actually really love answering questions about it because it's very, very interesting. And I am incredibly confused by it, and I don't get it."
Despite not going into great detail in the past, Billie has shared small glimpses into her life living with Tourette's.
Although she initially didn't want the public to know about her Tourette's, Eilish sat down with Ellen DeGeneres in 2019 where Ellen praised Billie for being so brave and upfront about sharing her condition.
The 20-year-old singer adds that she was diagnosed with tics at the age of 11 and that while some tics fade over time, the big ones, such as 'ear wiggling,' 'lifting her eyebrow,' and 'flexing her arm muscles,' occur throughout the entire day.
"These are things you would never notice if you're just having a conversation with me, but for me, they're very exhausting," she says.
"It's not like I like it, but I feel like it's part of me. I have made friends with it. And so now, I'm pretty confident in it."
Fans of the singer, especially those who live with the syndrome themselves, were grateful for Billie's honesty and her role in lessening the stigma.
Just another reason to love Billie!
