New York, Jan 16 : Pop star Madonna's daughter Lourdes worked a miracle, as she has made her mum and step-dad Guy Ritchie break the ice and become friendly post their bitter divorce.

Taking Lourdes' advice, Madonna and Ritchie are trying to be as friendly as possible.

"Madonna and Guy aren't reconciling," the New York Daily News quoted a source, as saying.

"They're working very hard to have an amicable divorce, because [Madonna's daughter] Lourdes came to them begging, `Please don't be mean to each other.' Then she told them she wanted everything to be as friendly as possible," the source added.
