Celebrity splits often end in bitter battles played out in the courtroom and the tabloids, but when lovers-turned-enemies have kids together, that's when things usually turn ugly.
Usher and Tameka Foster kick off our list of celebrity custody battles. After the couple's messy divorce was finalized in 2009, both parties fought for sole custody of their two young sons. Just weeks after Foster's son from a previous marriage (and Usher's stepson) Kyle Glover was tragically killed in a jet ski accident, a judge awarded Usher full custory of the boys. Now, after a pool accident sent their 5-year-old Usher Raymond V to the ICU, Foster is fighting to regain custody once again.
