i love you

"I Love You" is a heartbreaking acoustic cinematic ballad in which Billie Eilish describes what happened when her boyfriend told her "I love you." It's not true Tell me I've been lied to Crying isn't like you, ooh What the hell did I do? Though Eilish does love the boy, she is reluctant to express her feelings in words. Her response to her boyfriend's saying that he loves her seems to have upset him enough to have made him cry.

Eilish's brother and songwriting partner Finneas supplies the harmonies on the chorus.

Billie Eilish and Finneas performed a stripped-back version of "I Love You" on December 12, 2024, during a NPR Tiny Desk concert. "This is one of our favorite songs that we've ever written," Eilish said of the song. "It was the first time I fell in love and it was very scary. It's funny how that fear never goes away, that fear of falling."
