When Lizzo shines, everybody's gonna shine. And at Austin City Limits Music Festival, "everybody" was a lot of bodies, indeed.

The chart-topping rapper and singer played to massive crowd Sunday on the fest's Miller Lite stage starting at 7 p.m. By 6 p.m., a sizable audience had already gathered, and it exponentially grew as more and more fest-goers arrived. (See photos from the performance here.)

A visibly happy Lizzo mouthed the word "damn" when she looked out on the audience after her second song, "Worship Me."

"I want the people all the way in the back to know I see you, bitch," she said from the stage.

It wasn't until the fiery ballad "Jerome" that the sheer number of people gathered became apparent to those even halfway to the stage. Before that song, Lizzo asked that everyone light up their phones and put them in the sky. Points of light extended at least to the far end of the next-door Honda stage, where Cardi B was set to perform an hour later.

"This is the most insane, special crowd," Lizzo said after the song "Boys." "It may be one of the biggest crowds we’ve had at a festival." It was certainly one of the biggest non-headliner sets ever at ACL Fest.

Fans on social media couldn't stop talking about Lizzo's crowd size, with many saying that ACL Fest organizers should have booked her on a bigger stage. Lizzo's "Truth Hurts" did not hit No. 1 on the Billboard charts until after this year's lineup was announced. She previously played an early afternoon slot at the festival in 2016.

Here's what people are saying on social media.

If I was Cardi B, I wouldn’t wanna follow this. Lizzo killed it with the biggest crowd ACL has probably ever seen.pic.twitter.com/21nLqc9AnL

Lizzo’s crowd was insanely huge. Like 40,000 people for a non-headliner. Sadly her biggest song ‘Truth Hurts’ was a let down because practically every one was recording it on their phones. Like shit live in the moment people. Cell phones are slowly ruining the festival experience
