It seems only months ago that they were ecstatically in love, bouncing off the walls with happiness, making huge sacrifices for each other (he upped sticks across the world for her - I know men who wouldn't countenance a move out of Lurgan).
She did seem quite transformed - the anxious, nervy, defensive look she used to wear on her face (the wounded animal vibe which made her such a stressful creature to watch on the X-Factor) gave way to a post-massage, tension-relieved bathetic glow. When their baby came along she looked a picture of contentment in those early photographs, her youthful rosy face split with a grin so big you could cut down trees with it.
If the reports are to be believed - and the couple did release a statement saying 'Thanks for your concern. We're happy to be back at home in Melbourne together as a family. We are committed to our relationship and Ethan as always.' - things began to go wrong when Dannii failed to spot that committing to working, in Smith's hurt words, 'non-stop', hundreds of miles away from her boyfriend would have a detrimental effect on her relationship.
While Smith began to make a living in his wife's country, Dannii signed up to model, record a new album and promote her book, clothing range, talent show and perfume all over the world. She's the classic paranoid over-achiever, too conscious of a life of being overshadowed (by her sister and her celebrity peers) to allow herself to lie back and smell the roses.
Time's running out to wise up, Dannii.
