A friend told Britain's The Sun newspaper: "Madonna is convinced it is the right thing to do but Guy has been very wary."It has led to some serious arguments and put a lot of pressure on their marriage."His family are very concerned Madonna wants an African baby as a celebrity status symbol, like Angelina Jolie."Guy has adoption issues in his family and is all too aware of the problems. He doesn't think Madonna has really thought it through."Meanwhile, it has been reported that Madonna has already picked the orphan she plans to adopt, a one-year-old boy called Luca.The pop superstar - who already has a nine-year-old daughter, Lourdes, from her relationship with fitness instructor Carlos Leon, and son Rocco, five, with Guy - first met the boy at the Mchinji Mission Orphanage last Wednesday and on Saturday she returned to the home.It is believed Madonna has hired a top lawyer, Alan Chinula, to help speed up the adoption process - which usually takes six weeks.
