Boyle, from Blackburn, West Lothian, believes taking on a child would be a ''way of giving back for me''.
The Sunday Mail newspaper reported the singer as saying: ''I have so much love to give. I want to adopt a child who doesn't have much, who I can really give something to. It's a way of giving back for me.
''I have been considering it for a year. I love children, I always have but I couldn't have them. I want to give a youngster what I didn't have.
''We'll have to see what social services say, but it would make me so happy.''
She added: ''I know I'm single and 50-odd. People don't think I'm serious when I say it, they have a giggle at me. Let's see.''
Boyle, whose sixth album Hope is due out next month, is reported to have seen a relative care for foster children. While the singer said fostering would be ''great'', she added: ''You have to give them back, and that's what I would hate. With adoption, you don't have that wrench.''
