At the 2019 American Music Awards Sunday (Nov. 24), rapper Tyler, the Creator introduced BIllie Eilish's performance of "All the Good Girls Go to Hell" from her monster-hit album, when we all fall asleep, where do we go?, along with a humorous remark about the singer's style.

Before her performance, Tyler, the Creator said, "Earlier this year, my album Igor was the No. 1 album in the country...and then this seventeen-year-old girl who dresses like a quarterback decided to change that. Everybody give it up for Billie Eilish."

Watch the hilarious introduction, below:

The performance opened with Eilish singing alongside her brother Finneas O'Connell on acoustic guitar before she jumped around the stage as it burst into flames.

The "Bad Guy" singer has professed her love for Tyler, the Creator and his music many times. After he expressed interest in collaborating back in July, she wrote on Instagram, "i would be nothing without you tyler...everyone knows it."

As for Tyler's playful dig at the pop star's signature style, Eilish has commented on her baggy fashion in the past, including earlier this year in a Calvin Klein campaign video in which she addressed body shaming.

"Nobody can have an opinion because they haven't seen what's underneath," she said.
