Madonna and Guy Ritchie have reportedly been taking advice from Hollywood couple Brad Pitt and Angelina Jolie over the adoption process to be followed in respect of the 13-month-old Malawian boy.

Madonna and Ritchie have been in close touch with Jolie and Pitt from the early stages of the adoption planning. The couples discussed the adoption after they met at a London restaurant in January, when Pitt and a pregnant Angelina were staying at Claridge's, according to a friend in Los Angeles.

"Brad and Angelina know all about the adoption and have been helping Madonna and Guy in every way they can. They know how important it is to them and how difficult the process can be," the Daily Mail quoted the friend as saying.

It has also been revealed that the 'Material Girl'singer has reportedly hired a US adoption agency to adopt the 13-month-old Malawian boy, amidst fears that British authorities could try to stop her from becoming his mother.

Madonna and her husband Guy Ritchie could face a criminal investigation by British authorities after they brought David from Malawi recently.

Madonna, who is now 48 years old, could also face obstacles in the UK because of her age, but she is thought to be following US procedures where the rules are much more flexible about allowing older parents to adopt. (Source:ANI)
