"Strange Relationship" is the second solo single released by Australian singer Darren Hayes from his debut studio album Spin. The single was released in June 2002. The track was expected to be another hit single, and received enormous radio support in Australia, but it only just made it into the top 20 in Australia. The music video was directed by Tommy O'Haver. It features Hayes moving around a film set with a number of other people and changing scenery.
