Coachella 2026 - the largest music festival in the United States - has kicked off its first week with 3 performances from April 10-12 (local time) in Indio, California.
This year's main artists (headliners) include Sabrina Carpenter, Justin Bieber, and Karol G, whose performances have caused a storm on social networks.
In addition, the unexpected appearances of many celebrities at this festival also attracted the attention of global audiences.
On the evening of April 11 (local time), singer Katy Perry and former Canadian Prime Minister Justin Trudeau came to see Justin Bieber's music night. After that, on her personal page, the 41-year-old singer shared a series of photos and videos recording memorable moments with her boyfriend.

The two wore youthful and dynamic outfits. Katy Perry and Justin Trudeau both wore white t-shirts, the female singer combined black shorts and boots, and her boyfriend wore blue jeans and a backward baseball cap. Images of the couple holding hands affectionately quickly caused a social media storm.
On Tiktok, Katy Perry also shared a video of her and her boyfriend being extremely excited, jumping up and shouting when they saw Justin Bieber on stage. In another video, Katy Perry comfortably leaned on her boyfriend standing behind while he was swaying to the music of Bieber's song.
Many viewers were surprised because this is a rare time Katy Perry and Justin Trudeau have publicly appeared together at a major entertainment event.
Fans also discovered that in the video Katy Perry filmed with her boyfriend, the person standing right next to her was Lisa (Blackpink).
A day earlier, Lisa was scheduled to perform with Anyma at Coachella to promote the song "Bad Angel" that the two had just jointly released. But the stage was cancelled due to strong winds and safety reasons.

Today (Vietnam time), Rosé and Lisa were seen continuing to appear at Coachella to cheer for Big Bang. Blackpink and Big Bang members were once close artists with the management company YG Entertainment.
In addition, another viral video shows Lisa, Rosé (Blackpink) and actress Anya Taylor-Joy dancing and enjoying Sombr's performance.
Jennie (Blackpink) also appeared at Coachella this year. She reunited with Lisa and Rosé, but did not watch Big Bang's performance.
Besides, many other celebrities were present to cheer on the performing artists and participate in parties related to the festival such as Timothee Chalamet and Kylie Jenner, Kendall Jenner, Hailey Bieber, Cara Delevingne, Kim Kardashian and Lewis Hamilton, Paris Hilton, Camila Cabello, Central Cee, Gigi Hadid...
