Madonna and Guy Ritchie reportedly "screamed and shouted" at each other over a heated phone call, after the movie director failed to join her on her latest visit to Africa.

The 48-year-old singer returned to the Malawian orphanage with adopted 18-month-old David Banda and 10-year-old daughter Lourdes earlier this week.

Ritchie was expected to join Madonna with their son Rocco, six, but postponed the trip three times this week, allegedly sparking a tense row between the couple.

A source tells The Sun, "Madonna is furious with him. They fell out before she left London when he first postponed due to a last minute meeting. Since then Guy and Madonna have rowed over the phone, screaming and shouting at each other.

"She really hoped Rocco would be with her to see the kids at the orphanage."
