Now, however, in spite of the practicality of her short style, the Australian star has revealed a whole new longer look as she promotes the upcoming series of X Factor Down Under.
The mother-of-one, 41, was in Sydney for auditions for the fifth series of the show, and debuted her amazing new locks for promotional pictures for the next season.

Wearing her hair down in loose curls, the talent show judge has clearly had a little help with her fuller style.
It was, after all, only last week that the younger sister of pop icon Kylie, was spotted frolicking in Barbados with her famous pixie crop, a dramatically shorter 'do to her new longer length.
Down to extensions or a wig, there remains no doubt the Australian beauty has invested in the longer length – and she loves it.
Smiling widely alongside fellow judges, Ronan Keating and LMFAO’s Redfoo, Dannii appears more than happy with her new smooth mane.
Dannii joins X Factor Australia following Spice Girls Mel B’s departure due to legal complications.
Already having completed four seasons with the X Factor in UK, the popular star will no doubt thrive in her home land.
Last year, Dannii admitted mentoring and judging has been a "major part" of her life since 2007 and, with the announcement of her return to the UK to perform judging duties for Britain and Ireland’s Next Top Model, it doesn’t seem she will stop soon.
Joining Elle MacPherson and Tyson Beckford, Dannii revealed she had been brushing up on her “model moves” to ace her latest role.
The ninth series of BINTM will airs on Sky Living.
