Avril Lavigne rocks the stage at the Special Olympics opening ceremony

Avril Lavigne is flying high after rocking the stage with a crowd-pleasing performance of her single “Fly” at the opening ceremonies of the Special Olympics World Games in Los Angeles. The singer was in her element as she made her return to the stage after a challenging year away from the spotlight following a debilitating case of Lyme disease.

The blond beauty took the stage as the torch launching the games was lit, looking elegant in a charcoal-grey, beaded gown with her long locks shiny and straight. The star-studded opening ceremony also included an appearance by fellow Canadian Justin Bieber, actors Eva Longoria and Colin Farrell, swimmer Michael Phelps, singers Stevie Wonder and Cody Simpson plus First Lady Michelle Obama.

Avril's song has not only inspired athletes to believe in themselves and benefited the games financially, but Avril admitted to Good Morning America that “Fly,” “took on a whole new meaning for me during the time that I’ve been sick , which was pretty magical.” With lyrics like, “There's a light inside of all of us / soon you'll find that it's your time to fly,” Avril says that the song is about “inner strength and courage,” two things that she embraced while fighting her illness.

Prior to her appearance, the 30-year-old star kept fans up to date with her preparations, even taking to Instagram to ask for fashion advice. “I just sang FLY on stage for the FIRST time ALL THE WAY THROUGH live tonight in rehearsal,” Avril gushed on Instagram. “Making what feels like the impossible possible.”

Avril shared a snap with her team on Instagram, captioned "Team Lavigne ! Here we come #SpecialOlympicsOpeningCeremony #SpecialOlympicsLA2015"

Saturday’s performance comes after months of rest and recuperation for the Napanee native, who revealed in April that the reason for her absence from the music industry was due to a severe case of Lyme disease. “ I was bedridden for five months,” Avril told People magazine shortly after going public with her struggle. “I felt like I couldn’t breathe … I thought I was dying.” Fans will be happy to hear that the songstress is on the mend and has been busy in the studio working on new music with her husband Chad Kroeger, who has also been battling health issues and will undergo throat surgery this summer.
