Avril Lavigne And Chad Kroeger Capping Cannes Party Weekend With French Wedding

Singer and Nickelback frontman will cap three-day celebration with Monday night's (July 1) nuptials.

This time, Avril Lavigne, 28, is throwing a serious blow out. The singer is about to cap a three-day wedding celebration 
 in the south of France with a lavish wedding to Nickelback singer Chad Kroeger, 38. The happy couple and their wedding party have been living it up in Cannes since a rehearsal dinner on Saturday night in anticipation of Monday night's (July 1) nuptials.

According to E! News the ceremony will be held at an undisclosed location, with even the guests in the dark about the venue until they get picked up.

"[Avril] picked Cannes because she's spent significant time in Paris in the past few years and summered in places like St. Tropez," an unnamed source told E! "She's very immersed in French food, ambiance and culture. It's her favorite place to be." Lavigne previously told E! that she and Kroeger planned to have a "very big event," but one that will be limited to mostly friends and close family.

Last month, Lavigne revealed that the Canadian pair have written a new song together that will serve as their wedding theme and that she had big plans for her second trip down the aisle.

"I've been doing it, I'm the girl," she said. "I'm the one who has the crazy vision and he's letting me be me. It's a lot and I just want to make sure I really enjoy this amazing time ... I want all the guests who come to have this once in a lifetime experience and I want everyone to say 'Wow!' and for it to be special for everyone, not just us." Though the guest list isn't expected to be star-studded, among the bold-faced names who is said to be attending is former "X Factor" judge, and longtime mentor L.A. Reid.

It is the first time down the aisle for Kroeger and the second marriage for Lavigne, who divorced Sum 41 singer Deryck Whibley after three years of marriage in 2009.
