Today is the big day for Avril Lavigne and Nickelback’s Chad Kroeger! The couple is rumored to be tying the knot tonight in Cannes!

The couple made a whole weekend out of the festivities, inviting the wedding party to participate in a three-day celebration in the South of France, kicking it all off last Saturday. "[Avril] picked Cannes because she's spent significant time in Paris in the past few years and summered in places like St. Tropez," the source told E! News. "She's very immersed in French food, ambiance and culture. It's her favorite place to be."

After Avril, Chad and the crew enjoy their time together, the ceremony will be taking place tonight in a super-secret location. In fact, the wedding guests don’t even know where it’ll be happening! They’ll be picked up at a location and driven to the ceremony. Pretty cool, right?

This will be Chad’s first marriage and the second for Avril who divorced Sum 41 front man Deryck Whibley after three years of marriage in 2009.
