The 53-year-old star, who appeared on Britain’s Got Talent in 2009, told the Sunday Mail newspaper that having a child would make her “so happy”.
“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. We’ll have to see what social services say, but it would make me so happy,” she said.
Susan has reportedly already started the adoption process, but said many people think she is joking.
“I know I’m single and 50-odd,” she said. People don’t think I’m serious when I say it, they have a giggle at me. Let’s see.”
Last year, Susan told HELLO! magazine that she suffers from Asperger syndrome – a form of autism that affects communication and social interaction.
“It’s hard but having Asperger’s doesn’t mean I can’t get on with a normal life,” she said at the time.
“Any change in life, so quickly, is stressful because one minute you’re at home with your cat and the next you’re away with all of the camera people. Now I’m getting used to it; I have to get used to touring.”
