A statement by Natalie Imbruglia and Daniel Johns, who met in 1999 and were married on New Year's Eve in 2003, says: "We want to make it clear that our parting is amicable and we remain friends."
The statement added: "However, our career demands and our lives in different parts of the world have brought us to the point where unfortunately this difficult decision was necessary for both of us.
"We have simply grown apart through not being able to spend enough time together."
Natalie Imbruglia, who has been based in Great Britain, first found fame playing a role in Australian soap Neighbours, from which she launched her pop career.
Daniel Johns has been spending much of his time in Australia and with his band, and so the couple have been living on opposite sides of the world.
