Avril Lavigne is now officially Mrs. Nickelback, as she and the band's frontman Chad Kroeger tied the knot yesterday (July 1) in the South of France. It's apparently where all the pop-punk kids swap vows these days.

Despite reports that the Canadian couple politely wed over the weekend, Us Weekly reports via multiple sources that the actual ceremony occurred last night (the previous stories were apparently sparked by a pre-wedding bash).

"Yes, they're married," a source told the magazine, with a second chiming in, "It was a wild, all-night party with drinking, dancing, incredible food and lots of laughter and tears of happiness."

Highlights for the evening included a fireworks show over the Mediterranean and a late-night dance party with music ranging from Lynyrd Skynyrd to Bruno Mars.

"Avril and Chad had glasses of wine in their hands and were kissing as fireworks popped overhead and sparkled down," one party-goer gushed about the couple, who have been engaged since August 2012. "It was a magical moment and everyone was overwhelmed!"

"It was a truly amazing wedding, absolutely magical."

Mazel tov, you crazy kids.
