Madonna is open to adding to her sizable brood - insisting she would "never say never" to more children.
The Holiday hitmaker is already mum to Lourdes, 12, Rocco, nine, David Banda, three, and her newly adopted daughter Mercy, also three.
The singer is in a steady relationship with model Jesus Luz, who she has been dating since meeting at a photoshoot for W magazine in December (08), and she admits she wouldn't rule out having another child.
She tells PopEater.com, "Who knows? I have my hands full right now, I have no idea! That's all I'm going to say. But we never say never."
And with Lourdes nearing her 13th birthday (14Oct09), the Material Girl is proud of how well her eldest has coped with her three siblings.
She adds, "She's super-sister. She's amazing with the little ones. She has the typical relationship with her brother, Rocco. They're like 'I love you'/'I hate you' every five minutes. But with the two little ones, she's great. She's amazing. Very protective."
