The 'Here's To Never Growing Up' singer tied the knot with the Nickleback rocker in south of France, according to one of her close friend and colleague, reported Us magazine.
Mike Heller, CEO of Talent Resources, which represents Lavigne, wrote on his Twitter page, "I am in south of France about to see my little rock star Avril get married I am so happy to be part of this special celebration (sic)."
"No pictures will be sent since this is Avril's wedding but I will tell you everyone is so excited," he added.
"I feel most beautiful when I'm around Chad. He makes me feel so beautiful, and I'm not one who really dresses up that much. I'm usually in the studio in regular, comfy clothes. I wear some pretty out-there designs. He likes my style - he thinks I'm cute," Lavigne had said.
