Madonna has received a message of support from Wolverine star Hugh Jackman over her continued efforts to adopt four-year-old Malawian girl Mercy James.
The Aussie actor, who has two adopted children of his own, hit out at cynics who questioned Madonna's motives for wanting to adopt a second child from the African country. "I'm sure she is coming from a good place," he said.
"I challenge anyone who thinks you adopt a kid for a publicity stunt. Any parent knows that would have to be the most intensive publicity stunt in the world."
His comments came as the Material Girl's bid to make Mercy a permanent member of her family suffered a further complication this week when a man claiming to be Mercy's father moved to claim full custody of his daughter.
Twenty-four-year-old James Kambewa, who says he was unaware of the child's existence and was told she died in childbirth with her mother, has written a letter to lawyers asking for a permanent injunction to prevent the 50-year-old adopting her.
"I don't think Madonna is a model mum," the security guard - who is willing to take a DNA test to prove he is Mercy's dad - told the Daily Mail. "She doesn't portray good morals."
In a handwritten letter Mr Kambewa says: "I do not consent to the adoption because I feel I am capable of raising the child." He says he has also called on the help of the Human Rights Consultative Committee, a group of organisations which have taken issue with the adoption.
Madonna's adoption application has been turned down by a Malawi court, but sources say she is "confident" of overturning the decision in an appeal next Monday. She had hoped the fact she had the backing of key members of Mercy's immediate family, including her grandmother and uncle, would help.
