Avril Lavigne Returns To The Stage At 2015 Special Olympics

It's the first performance in a year for the singer, who revealed last month she is fighting Lyme disease.

Avril Lavigne is back!

The 30-year-old singer took to the stage Saturday to perform her new single "Fly" at the 2015 Special Olympics World Games in Los Angeles. The performance -- which she nailed -- was her first since she revealed her battle with Lyme disease. 

Last month, the Napanee, Ontario, native opened up about living with the illness, saying it left her bedridden, on an episode of "Good Morning America." Lavigne is going through treatment, she said, and believes she'll make a full recovery. 

The Canadian star shared an Instagram post after the performance expressing her gratitude and excitement at being able to take the stage. 

She wrote a moving caption:

"Honored to have performed my song Fly at the opening ceremony for the Special Olympics tonight. All proceeds go to support the Special Olympics. 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."

Other stars who came onstage at the opening ceremony included Nicole Scherzinger, Eva Longoria and Stevie Wonder as well as Michelle Obama and Maria Shriver.
