Congrats to Avril Lavigne and Nickelback frontman Chad Kroeger! The pride and joy for the Great White North have tied the knot after a whirlwind romance, lots of hair dye and quite a few collaborations.
Avril Lavigne and ex-husband, Sum 41 frontman Deryck Whibley, have had a friendly relationship even after their divorce -- they worked together on a few of her albums -- so when Whibley donned a Lavigne costume for Halloween, fans weren't sure if it was an honor or a dig to the 'Girlfriend' singer. And apparently neither was her new fiance.
