It is that time of year again: Coachella! And this year, the iconic musical festival has some controversy brewing with none other than pop darling Sabrina Carpenter! The 26-year-old singer headlined Coachella for the first time in Indio, California, on Friday night, and she sparked backlash for her reaction to a fan's cultural Arabic cheer, which is typically a high-pitched tongue trill used in celebration. A video of the incident posted on X (Twitter) showed Sabrina sitting at her piano onstage when she suddenly heard from someone in the crowd what sounded like an ululation.
