While her debut album might have only arrived in March, Billie Eilish had no trouble filling Chicago's United Center on Sunday, with a massive, sold-out crowd showing up to watch the 17-year-old breakout star perform.

She has been on the road in support of her debut record When We All Fall Asleep, Where Do We Go?, which has spent multiple weeks at No. 1 on the U.S. Billboard charts. In fact, it returned to the top just this past week, months after its original release.

Following her Coachella debut in April, Eilish kicked off her tour—which is entirely sold-out—in San Francisco. In addition to the Chicago stop, she has upcoming shows in Boston, Philadelphia, New York, Nashville, multiple dates in Los Angeles and a finale in San Diego.

As we previously mentioned, Denzel Curry is on the road supporting Eilish on select dates of the North American trek. He opened for the United Center show.
