Rocker Jack White and his model wife Karen Elson are doing something special to honor their 6-year wedding anniversary -- they're getting DIVORCED ... and throwing a huge party to celebrate!
The couple announced the split in a joint statement -- saying, "In honor of that time shared, we are throwing a divorce party."
The big post-marital bash -- which will feature "dancing, photos, memories and drinks with alcohol in them" -- takes place tonight in Nashville.
The 35-year-old rocker married Elson -- also a musician -- in 2005. They have two children.
