The 'Here's To Never Growing Up' singer tied the knot with the Nickleback rocker in the south of France, according to one of her close friends and colleagues.
Mike Heller, CEO of Talent Resources, which represents the Canadian signer, wrote on his Twitter page on Saturday morning: ''I'm in south of France about to see my little Rok star #avril get married I am so happy to be part of this special celebration. (Sic)''
He later added: ''No pictures will be sent since this is #avril wedding but I will tell you everyone is so excited.''
The 28-year-old singer previously revealed she was planning a lavish wedding, saying: ''I just want to make sure I really enjoy this amazing time and I want all the guests who come to have this once in a lifetime experience. I want everyone to say, 'Wow!' and for it to be special for everyone, not just us.''
The 'Girlfriend' singer, who was previously married to Sum 41 star Deryck Whibley, fell for Chad, 38, last summer when he was helping her record her fifth studio album.
She recently said: ''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.''
