Relations between Madonna and ex-husband Guy have been somewhat frosty since their breakup.
But an invitation for Guy to meet new adopted daughter Mercy has caused a thaw between the pair.
Malawian Mercy James arrived in Britain last weekend and Guy spent much of Friday night bonding with his ex-wife and her daughter, according to the Daily Mail.
Friends say that the 40-year-old movie director has 'fallen head over heels' with Mercy and nicknamed her Koala as she clings to anyone holding her.
When Madonna first thought of adopting another child, it came as the final straw for Guy. With their marriage already in crisis, Guy was said to be against the adoption and the couple later divorced.
But as the dust settles, it seems Madonna is keen for Guy to remain part of the family and she has reportedly invited Ritchie to spend time with Mercy over the summer.
A source told the Mail: "Guy is at Ashcombe, his house in Wiltshire, with his sons David and Rocco, but Madonna has told him he is welcome at the house in London.
"Madonna's 12-year-old daughter Lourdes really misses Guy. She adores him and has been instrumental in encouraging her mother and Guy to get along.
"She is old enough to read the papers, and she hated the fact that they were having a go at each other in the Press. She told them to stop it. Since then Madonna has been making a real effort.
"She is desperate for this adoption to be seen as a success, because she has set her heart on adopting more children."
Madonna is obviously keen to extend her family. Check out who else is taking the adoption route..
