Billie Eilish says her new documentary is hard for her to watch, here’s why!

For Billie Eilish, her upcoming documentary is an emotional rollercoaster. During the episode of The Late Show with Stephen Colbert, the There I Am singer discussed her documentary Billie Eilish: The World's A Little Blurry and how authentic she was during filming – so much that she struggled to watch it. "I think it's important for people to know that it's not all that was going on," she explained. "There's a ton that isn't in there, but it's pretty much me. And it's kind of a huge bummer because I was super annoying then." Since Billie doesn't change how she acts when cameras are turned on, she was "very worried" about the film's final outcome. "The first cut was three hours long. Took us about five hours to get through the whole thing because we kept stopping it," she recalled, noting that she was shocked by what they viewed each time. Billie Eilish: The World's A Little Blurry is set to release in theaters on February 26.
