Kylie Minogue is planning to adopt a baby with her Spanish boyfriend.

The Australian singer, who is currently dating model Andres Velencoso, is apparently inquiring about how they can take custody of a child.

Kylie, 42, is feeling broody after her sister, Dannii, 38, announced to have her first child Ethan with ex-Leeds rugby league player Kris Smith, 32.

"Kylie is aware she will have difficulties conceiving naturally due to her age and the fact that she underwent chemotherapy to fight breast cancer five years ago," a source told British newspaper The People.

"But she is really desperate to have a family. She is so happy for Dannii and has vowed to be a great auntie but what she wants is her own.

"She is aware that she isn't getting any younger and has admitted to herself and Andres that having their own kids could be near-on impossible so they have discussed the idea of adoption and are to see how they can take the idea forward.

"At the moment, the big likelihood is that they will adopt a child. They have yet to decide where from or how but it is a big priority of theirs now."
