Touching down at Heathrow Airport early Wednesday, the 57-year-old pop star donned all black and covered her eyes with a pair of dark, Wayfarer-style sunglasses. Rocco is living with his father in London – after he reportedly refused to fly back to New York to be with his mother late last year. In March, a New York Supreme Court judge said the teen could continue staying with Ritchie while his parents work to find a solution outside of court. A U.K. High Court judge ruled last month that the custody case must be determined in the U.S. The British judge also urged the famous exes to reach an agreement together outside of court. The next hearing is tentatively scheduled in New York for June 1. Madonna v. Guy Ritchie: Timeline of Their Custody Battle Madonna and Guy Ritchie first began battling over Rocco’s living situation in December, and filed legal cases in both U.K. and U.S. courts. Madonna toured throughout the ordeal, facing speculation over her physical and emotional health – rumors a source previously slammed to PEOPLE. “She continues to be a pillar of strength even as she has shown a more vulnerable side,” the source said. “It’s unfair that both men and women feel they need to give their opinions on the kind of parent they ‘feel’ Madonna should be because she isn’t like most parents: Not every parent can work as hard as she does without being put under a microscope, and most parents don’t have outrageous stories about them made up by the media on a daily basis.”
