Madonna's 19-year-old daughter has stepped in to mend the rift between her mother and brother.
Lourdes Leon - whose father is fitness trainer Carlos Leon - is concerned about the deteriorating relationship between the Hung Up hitmaker and 15-year-old Rocco, who is now living in London with his father Guy Ritchie, so is attempting to make piece between the pair and be a point of contact for them both.
A source told The Sun newspaper: "Lourdes is very concerned about her mother.
"Madonna has no official access or way of knowing what's going on in Rocco's life.
"She also can't get direct contact with Guy. He wants to conduct all their business through lawyers.
