AceShowbiz - Chappell Roan looked unrecognizable when attending Charli XCX and Troye Sivan's "Sweat Tour". The "Good Luck, Babe" singer was spotted among the crowds at Charli and Troye's tour stop in Los Angeles on Wednesday, October 16.

For the casual outing at Kia Forum, Chappell donned a long, jet black wig. The 26-year-old opted out her usual drag makeup for the toned-down night out as she only wore dark eyeliner and nude lipstick color.

Roan's creative director Ramisha Sattar took to Instagram to share a short video of Chappell at the music event. The "Hot to Go" hitmaker seemed to be enjoying her time as she was beaming that night.

Joining Chappell, other notable figures in attendance at the show were Katy Perry, Lily-Rose Depp and her girlfriend 070 Shake. "Vanderpump Rules" star Ariana Madix, singer Madison Beer as well as Barack Obama's daughters Sasha and Malia Obama were also among the concertgoers.

In other news related to Chappell, actress Brie Larson shared her impression after meeting the musician while hanging out with Saoirse Ronan. On Thursday, the "Captain Marvel" star took to her Instagram to share pictures of herself, Saoirse and their pals posing with Chappell after one of her recent concerts in Europe.

Brie could be seen wearing a furry red headpiece while hugging Chappell and her mother Kara Amstutz. "Simultaneously not ok and never been better @chappellroan," the 35-year-old actress wrote in the caption.

The post quickly sent fans into a frenzy with one commenting, "The insanity of this pic is overwhelming omg." Another said, "omg chappell, brie larson and saoirse in one frame."

One user cheekily wrote, "my favorite artist and my favorite artist's favorite artist." Meanwhile, one user demanded, "ENVY ADAMS - CHAPPELL ROAN COLLAB WHEN," referring to Brie's character on "Scott Pilgrim vs. the World".
