Billie Eilish is a GRAMMY award-winning singer, a fashion icon, a dedicated advocate and a person with Tourette syndrome -- and she says her diagnosis is a part of what makes her, her.
Opening up to David Letterman on season 4 of his Netflix series, My Next Guest Needs No Introduction, the "Happier Than Ever" singer shared details on her neurological disorder.
The "Bad Guy" singer says she experiences physical tics that have just become synonymous with who she is because they are so frequent.
The 20-year-old singer says that the tics tend to subside when she is focusing on something and moving around, which is why she doesn't have tics on stage while performing.
While it's clear Billie's Tourette syndrome has not stopped her from achieving success, she does say that before being famous she felt more alone in her diagnosis.
“What’s funny is so many people have it that you would never know,” Eilish said. “A couple artists came forward and said, ‘I’ve actually always had Tourette’s.’"
