Madonna was reunited with her son Rocco on Sunday after appearing to strike a custody deal with her ex-husband Guy Ritchie.
The former Hollywood couple has been locked in a bitter legal battle since December, when 15-year-old Rocco refused to return to his mother's home in New York in favour of staying with his filmmaker father in London.
Judges in both cities ordered Madonna and Ritchie to work together for the sake of their boy, and the pop superstar, who recently completed her Rebel Heart World Tour in Australia, was photographed arriving in the UK capital on Thursday for peace talks with her ex.
The discussions seemingly went well as Ritchie was photographed dropping Rocco off at his mum's London mansion on Sunday for a visit. The teenager was also spotted smiling as he emerged from Madonna's pad two hours later to go skateboarding with a friend.
Details about the reported custody agreement have yet to be revealed, but Madonna hinted that things were progressing in an Instagram post on Thursday, when she shared a selfie and captioned it, "YES! Good things are coming!".
The mother and son reunion occurred days after Ritchie and Rocco returned from a family vacation in the Maldives, where they relaxed with the director's new wife, Jacqui, and their three young children.
Madonna and Ritchie are due to appear before a New York family court judge in June, when their lawyers are expected to outline a custody deal.
The singer has yet to comment on her son's visit, but she shared her heartache over her personal problems with fans on tour. In a special set in Melbourne last month, she dedicated the track Intervention to her eldest boy.
"Everybody knows the saga of me and my son Rocco," an emotional Madonna explained to the crowd. "It's not a fun story to tell or think about. I probably would have enjoyed myself a bit more on this tour if he hadn't have disappeared so suddenly. I'm going to dedicate this song to him."
Madonna has been vocal in her desire for her son to return to New York often using Instagram to convey emotional messages, however, the source claims Rocco feels "she is more concerned with proving Guy wrong" and less concerned with what he actually wants.
The location and date of the meeting have yet to be decided but Madonna is keen to make progress ahead of their scheduled 1 June court date.
Madonna was granted primary custody of Rocco after splitting from Ritchie in 2008. The pair are also parents to adopted son David, 10, who attended Ritchie's wedding to Jacqui last August. The pop star is also mum to daughters Lourdes, 19, and Mercy, 10, who was also adopted.
