VIDEO : Madonna Posts Loving Throwback Photo of Son Rocco Amid Custody Fight

Madonna is showing love for all her kids this Christmas, even including eldest son, Rocco Ritchie, as she and his father continue their custody battle over the teen. The 57-year-old Queen of Pop posted on her Instagram page on Friday, Christmas Day, a photo of herself and the 15-year-old boy at her birthday party this past August. She wrote, "Merry Christmas to the Sunshine of my Life!" Rocco's father is film director Guy Ritchie. Madonna and Guy have been battling it out in the New York City court system over who Rocco should live with. A judge recently ordered Rocco to spend Christmas in New York, and for the parents to stop discussing the custody battle with their son.
