Madonna and her film-maker husband Guy Ritchie are planning to start searching for a child to adopt in October (06), once the pop superstar finishes her Confessions world tour. The MATERIAL GIRL - who already has two children, LOURDES, nine, and ROCCO, five - wants more kids so the couple have hired the adoption lawyer who worked for their friends Brad Pitt and Angelina Jolie. The 47-year-old singer and Ritchie have also talked to adoption agencies in both the US and the UK. An insider tells British newspaper The Sun, "Madonna and Guy are serious about adopting a baby. They had a meeting with a British adoption agency but were not satisfied that it was the right one. "So they found another agency in America and had a meeting with them about becoming parents to an orphaned baby. "They both love children and are desperate to expand their family." Earlier this week (begs17JUL06), Ritchie's father John Ritchie said, "I love my grandchildren, and of course nothing would make me happier than if they do adopt. "How lovely to have another one, it sounds like such great, great fun. "I'm sure both Rocco and Lourdes would love it as they are so close and another sibling would be super."
