Sia beamed her performance of "Bird Set Free" from South by Southwest in Austin to Jimmy Kimmel Live! in Los Angeles Monday.
Though Sia's face was covered by her signature wig and oversized bow during the performance, she exuded confidence while singing her recent This Is Acting single. Accompanied only by a sole male dancer, Sia stood still as she soared through the performance of the song, which she revealed last year was originally meant for Pitch Perfect 2 before getting turned down, then sent to Rihanna, who sent it back, then finally Adele, who also passed, Rolling Stone reports.
"I could not believe they rejected 'Bird Set Free' because to me it was such a big, anthemic, fun, sing-along-in-the-car song," Sia said. "I felt seller's remorse. I had grief. I feel connected to that song."
