As Jon and Kate's bitter battle continues, look back at other families who took their fights public
Britney Spears and Kevin Federline
After ending their two-year marriage in 2007, they fought bitterly over sons Sean, 4, and Jayden, 3, as Spears' mental health deteriorated. Today, Federline has sole legal and physical custody and receives $20,000 a month in child support; a healthier Spears has gotten more visitation rights.
