"Wildflower" is the fifth track from Billie Eilish's third album, Hit Me Hard and Soft. Soulful and gloomy, it recounts her experience comforting a girl after a difficult breakup. But plot twist! Feelings blossom, and suddenly Eilish finds herself tangled with that same girl.

Eilish and Carlson became close and were photographed holding hands at a Halloween party. The second verse drops a big hint. I'd never ask who was better 'Cause she couldn't be More different from me Happy and free in leather Carlson is frequently seen wearing leather clothing.
