While Billie Eilish's new documentary is going to be a one hour plus treat for her fans, the singer has admitted she's found it difficult to watch it back herself.

Billie, 19, appeared on The Late Show with Stephen Colbert this week to discuss the Apple TV+ doc titled Billie Eilish: The World's a Little Blurry, and dished on what we can expect.

The singer began by saying she loved the filming process and getting to document her life, explaining: "It was fun to have people there that are literally just there to watch you live your life, because there’s nothing like that. There’s nothing in life that is like that. It was very fun and I kinda loved it, to be honest with you. It was a lot at times, but it was also fun.”

Billie also warned viewers they should be "very conscious of the fact that it’s not everything. You’re seeing a sliver of my life at that time."

But even though there's a lot we don't get to see, she added that "it's pretty much me and it's kind of a huge bummer because I was super annoying then. It's rough. It's hard for me to watch."

From award-winning filmmaker R.J. Cutler, it tells the true story of the singer-songwriter's rise to global superstardom after she released her debut single 'Ocean Eyes' in 2016. With cameras following her for three years, we get to see candid moments of Billie at home with her family, enjoying life on the road and making her debut album.

We can't wait to watch it.

Billie Eilish: The World’s A Little Blurry is released on Apple TV+ this Friday 26th February.
