The baby boy that Madonna is hoping to adopt has landed in the UK and been taken to the singer's London home.
Madonna wants to adopt a one-year-old boy from Malawi in Africa called David Banda, who was living in an orphanage.
Madonna will be allowed to be his mum for the next 18 months while officials in Malawi decide if they will give her permission to adopt David.
A group of charities in Malawi have joined together to try and stop the singer from becoming David's mum.
They think that because Madonna is famous some of the rules that are normally followed in adoptions have been broken.
The law in Malawi says anyone who wants to adopt a child there must live in the country for 12 months and children are not supposed to be adopted by people not from Malawi.
David lived in an orphanage after his mum died when he was born.

His dad is still alive, but has agreed that Madonna can adopt his son.
One of the charities against the adoption - Eye of the Child - said it wanted to make sure the future of a person who is not old enough to say what they want is safe.
