Billie Eilish recently confirmed her relationship with Jesse Rutherford.
The singer flooded Instagram with pictures of her Halloween celebrations.
Amid these snaps, was her Halloween costume with Rutherford.
The pair dressed up as a baby and an old man.
However, fans found this concept "disgusting."
Several people slammed Eilish for joking about pedophilia.
The songstress's costume may have been aimed at critics.
Rutherford has a 10-year age gap with Eilish.
Speculations of the couple's romance began in October 2022.
