While the "Don't Go Yet" singer was all smiles on the red carpet at the Aug. 30 celebration, she briefly "passed out" before taking the stage inside The Greek Theatre in Los Angeles. "I'm sorry, I just passed out, but I'm back!" Cabello, 24, told the audience as she joined co-stars Billy Porter, Idina Menzel and more on the stage. "I literally just passed out, and now I'm back and I'm ready to read my notes."
While Cabello didn't share any additional details on the fainting incident, E! News has reached out to her rep for comment.
Despite the brief scare, Cabello powered through her speech and thanked the crowd for coming to the premiere. "All I can say is this was such an incredible experience," she told the audience. "I believed in this movie so much, that all I wanted was to enjoy it and not f--k it up. And I'm happy I didn't f--k it up. And I'm grateful for everybody who believed in me enough to give me the opportunity."
Before heading inside to the premiere, Cabello—who takes on the titular role in the magical Amazon Studios film—stopped to talk to E!'s Daily Pop on the red carpet. In addition to gushing about Cinderella, the Grammy nominee also dished about going viral with James Corden for the late-night host's Crosswalk: The Musical video.
In one clip posted to social media over the weekend, the Cinderella cast could be seen dancing in the street with Corden, who was dressed in a mouse costume. "Oh my god it was crazy, I've never done anything like that before," Cabello said. "And I loved the videos that I saw of the fans, just like from inside their cars. It was fun to relive the songs, too."
While we wait to see the finished product, take a look at the red carpet fashion from the Cinderella premiere below.
