Lady Gaga’s Mayhem Ball has officially hit stages across the world, from Coachella to her record-breaking Copacabana show that drew in a crowd of nearly 2.5 million people. Of course, Mother Monster’s iconic live performances have been a safe space for all kinds of people, from devoted Little Monsters to fellow A-listers. Whether it’s Ariana Madix chilling in the artist section at Gagachella or Katy Perry catching Gaga’s Viva La Mayhem show in Mexico, one thing is certain: Gaga draws in quite the crowd.
That very theory was proven once again during the “Abracadabra” hitmaker’s tour stop at the Kia Forum in L.A., where seemingly every Gen Z it-girl and her entourage were in attendance. Ahem: Pop’s newly minted princess, Addison Rae, was spotted leaving the venue with Olivia Rodrigo, who lived it up in the stands with her bestie, Conan Gray. Those are only a fraction of the names who pulled up to witness the opera house in all its glory. Ahead, find every celebrity who attended Lady Gaga’s Mayhem Ball in L.A. on July 29.
Halsey and Avan Jogia
The “Nightmare” singer shared a TikTok in her signature blue locks and an all-leather look, captioned, “going to see mother!” with her fiancé, Avan Jogia.
Gerard Way
The My Chemical Romance frontman may be on his own tour right now, but that didn’t stop him from seeing Gaga at her second concert at the Kia Forum.

Olivia Rodrigo, Conan Gray, Madison Hu, and Chappell Roan
It looks like O-Rod’s group chat made it to the Kia Forum, as they were spotted dancing along to “Born This Way” in a private section. Chappell Roan was also in attendance, per iHeartRadio.
Addison Rae
It’s no mystery that Addison joined the Mayhem as a longtime Little Monster. Not only does she give Gaga a shoutout on her track “Money Is Everything,” she also dressed as her for Halloween in 2022. And, as fate would have it, Gaga wrote Addison’s 2023 song, “Nothing On But the Radio.”
