The battle over their teenage son became a war of the picture album for Guy Ritchie and Madonna.
The former couple traded photos on the Instagram social network to try to show who had the better Christmas.
Ritchie's new wife Jacqui posted a picture of their wedding day in July with Rocco standing by her side smiling and the caption "Happy holidays with love from the Ritchies".
The couple's three children are also in the shot, as is David Banda, ten, whom Ritchie and Madonna adopted before they divorced in 2008. Meanwhile, Madonna posted an old one of her and Rocco with the caption: "Merry X-mas to the Sun-shine of my Life!"
