Kesha Joins Charli xcx for Live Debut of 'Spring Breakers' Remix at Los Angeles Concert

Charli xcx brought out the "club classics" — and Kesha — in Los Angeles.

On Tuesday, Oct. 15, the "Good Ones" singer, 32, brought her and Troye Sivan's joint Sweat Tour to the Kia Forum, where she had a few surprises in store for fans.

After sharing the remix of "Spring Breakers" on Monday, which features the "Praying" artist, 37, Charli invited Kesha to perform the track with her onstage for its live debut.

Per fan-captured footage, the British pop star delivered the first verse of the track before the "Joyride" musician appeared in a pink fur coat.

Also during the show, Charli and the "One of Your Girls" hitmaker, 29, joined Kesha for a performance of her 2009 classic "TiK ToK."

That wasn't the only unexpected guest at the concert.

During Sivan's set, he invited Tate McRae to join him for "You," their collaboration with DJ Regard.

Charli and Troye — who collaborated on "1999" and "2099" off the 2019 album Charli — kicked off their arena tour across the U.S. and Canada in Detroit on Sept. 14.

The superstars have made stops at iconic venues like New York City's Madison Square Garden and Los Angeles' Kia Forum, in addition to major cities like Philadelphia, Boston, Chicago and more. The shows will wrap on Wednesday, Oct. 23 in Seattle. 

Throughout their run, Charli xcx and Sivan have enlisted British alt-hip-hop/electronic star Shygirl as their opening act.

The pair have invited a handful of surprise performers onstage with them throughout the Sweat Tour.

On Sept. 24, Addison Rae made her live performance debut of "Diet Pepsi" at Madison Square Garden in N.Y.C. When she reached the chorus, Charli and Sivan joined her to sing some of the lyrics, per fan-captured footage.

Charli then performed her track "Girl, so confusing," which was actually the remix. Near the end of the track, Lorde joined her onstage to sing with the "Vroom Vroom" artist, per fan-captured footage.

Another surprise guest at the show was Kelley Heyer, who created the viral "Apple" dance. She appeared on the big screen to highlight her signature dance moves in a brat-emblazoned skirt for the entire crowd.

Charli released her remix album Brat and it's completely different but also still brat on Friday, Oct. 11.
