London: Singer Madonna's 19-year-old daughter Lourdes Leon has stepped in to mend the rift between her mother and brother Rocco.
Madonna is currently in a custody battle with estranged husband Guy Ritchie for Rocco, and at a recent concert, she became emotional about missing him. It seems Lourdes keeps Madonna informed about Rocco.
"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 (Ritchie). He wants to conduct all their business through lawyers," a source told The Sun newspaper, reports femalefirst.co.uk.
"Madonna is so proud of Lourdes, she believes she is proof of what a brilliant mum she was because she is now at university," the source added.
Rocco left the 'Vogue' hitmaker's Rebel Heart tour late last year to be with his father, stepmother Jacqui Ainsley and three half-siblings here, and later defied a court order to return to the US to spend Christmas with his mother.
Last week, a judge ruled the teenager should stay with the 'Man From U.N.C.L.E.' filmmaker for the time being in order to prevent his schooling from being disrupted. The former couple have also been advised to make an amicable agreement over custody of the youngster.
It was claimed at the weekend that Madonna, who also has adopted kids Mercy and David, both 10, is resigned to Rocco living with his father permanently, but has insisted on imposing a number of conditions regarding rules, structure and security, if that is to be the case.
