The iconic singer - who was adopted at a young age by shop owners Richard and Catherine Harry - has never had children but did occasionally think about the idea of expanding her family.

She said: "I`ve thought of adoption, which I think I`d be really good at. Now that this terrible earthquake has happened in Japan, there will be lots of children needing homes."

The 65-year-old pop star likes to support various charities, and the eco-conscious celebrity would like to set up a foundation to promote the use of solar panels.

She said: "I spread myself around a lot of causes.

"I`m concerned about the environment and clean water and being carbon-free. I also support diabetes research.

"If I were to do a foundation it would be to promote solar energy. And I`m worried about drilling for oil. I think it is harming the earth, because it drains the layer of oil under the surface, and that could be causing earthquakes.

"It`s like we`re giving the earth arthritis. I don`t know if that sounds crazy."
