Watch Charli XCX Bring Troye Sivan & Kim Petras on Stage at LA Concert

Popstar Charli XCX rocked Los Angeles this week with two incredible performances.

On Thursday, XCX headlined Tinder's Festival Mode Launch Party, performing bangers off her new album Crash alongside iconic tracks "Boys" and "I Love It." The event celebrated the return of IRL music festivals and the upcoming announcement of the app's Festival Mode feature, launching on April 14th. 

The 15-minute set was just a taste of what she'd deliver Sunday night during her headlining show, and she certainly knows her fans are largely LGBTQ+. "I know it’s the Grammys tonight but it’s also my sold out show at the Greek in LA tonight which is essentially the gay Grammys where I win every award," XCX tweeted. "So yeah."

She certainly delivered on the "gay Grammys" promise. A.G. Cook and Baby Tate opened the show, then she brought out two special guests to the stage that fans lost their minds over.

XCX welcomed Troye Sivan out to perform "1999".

And Kim Petras rocked "Unlock It".

"Bunny is a Rider" herself, Caroline Polachek was also in attendance and mouthed every word to "New Shapes" from the audience.
