As Jon and Kate's bitter battle continues, look back at other families who took their fights public
Whitney Houston and Bobby Brown
When not smoking crack-laced marijuana together, the pair -- who split in 2007 -- got into such intense fights during their 14-year marriage that Brown spray-painted "evil eyes" in her bedroom wall and once "spit" on her, Houston claims. She has full custody of daughter Bobbi Kristina, 16.
