Avril Lavigne took the stage at the opening ceremony of the Special Olympics in LA on Saturday night to deliver a heartwarming performance of her new single "Fly." It was an especially meaningful moment for Avril, since it was her first performance after opening up about her battle with Lyme disease in 2014. The singer, who stunned in a black floor-length gown, took to Instagram following her time on stage to write: "Honored to have performed my song Fly at the opening ceremony for the Special Olympics tonight. . . . This was a very beautiful night for me. Congratulations to all the athletes. Thank you to everyone who supports the Avril Lavigne Foundation. It has been a difficult year fighting through Lyme Disease for me and I am so happy to have made it on stage tonight for the first performance in a year. Thank you for having me and please enjoy my song Fly. I wrote this song to encourage people who are facing challenges, to encourage strength and to empower. Xoxo."
