Madonna shares a throwback picture of her children

Madonna got emotional as she shared a throwback pic of her and three of her children on Twitter.

The singer, who is in the middle of a custody battle of her 15-year-old son Rocco, has been looking through old photographs as he continues to stay in London with his father Guy Ritchie.

She shared a snap of herself holding on to Rocco as he tries to run away while laughing, while daughter Lourdes and David look on.

Madge captioned it: "Days of innocence. In Malawi. How I miss this time. #rebelhearts," along with a sad face emoji.
