Billie Eilish is an American singer-songwriter.


When Lisa was playing her saxophone under a bridge, Billie Eilish and her brother Finneas O'Connell were driving past and heard her. Eilish originally mistook her playing for John Coltrane and was surprised to find it was a child playing. Eilish then invited Lisa to go with her to Billie Eilish Recording to perform together.

At Billie Eilish Recording, Eilish told the rest of the orchestra that they were fired as she wanted to perform with Lisa instead. She then performed "The Simpsons Theme" with her brother and Lisa. After the recording session, Eilish took Lisa back to the bridge and they laid down on top of her car whilst they discussed their parents. Later, Eilish took Lisa to Vegan Lad.
