After enduring a rough patch in their relationship, Madonna and husband Guy Ritchie are stronger than ever and are even considering adopting a child. Guy's father John Ritchie caused headlines earlier this year (06) when he spoke about the celebrity couple's marital strife, but now claims the family is back together. He tells American publication In Touch Weekly, "Their marriage is back on track. I know that Madonna is away a lot at the moment and leaving Guy alone, but it just isn't a problem. "He knows that will happen and he is not worried about it at all. He doesn't mind her working. Their marriage is back on track." The elder Ritchie even addressed rumours that the couple may be adding to their family saying, "I love my grandchildren, and of course nothing would make me happier than if they do adopt. "How lovely to have another one, it sounds like such great, great fun. "I'm sure both ROCCO and LOURDES would love it as they are so close and another sibling would be super."
