Avril Lavigne and Nickelback's Chad Kroeger put a rock and roll spin on traditional wedding attire as they exchanged vows in the South of France Monday.
Hello! Canada exclusively reports that Lavigne, 28, wore a black tulle Monique Lhuillier gown and donned a bouquet of black roses.
The pair made it official just outside the Château de la Napoule, a 14th century castle in the provencal town of Mandelieu, according to E!, adding that the ceremony was just a small part of a three-day celebration that kicked off with a rehearsal dinner in Cannes Saturday night.
Despite the European nuptials, the Canadian rockers paid homage to their native land when they got hitched on Canada Day – which also happens to be the date the couple started dating a year ago.
"We think it's very cool that our anniversary will always be on Canada Day," Kroeger told PEOPLE in September. "We can't wait to start our life together. We're very happy."
