A source close to the Avril camp tells PEOPLE that the wedding did not happen Saturday.
Word had spread after E! News, quoting a source, announced that the nuptials had taken place. The Daily Mail also cited a Tweet by Mike Heller, the CEO of the talent company that represents Lavigne.
Saturday morning Heller posted: "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."
PEOPLE.com earlier on Saturday had posted news of a wedding based on those reports.
