We haven’t heard those Big Brother “it’s time to go” words for a while, but it’s now come time for Gretel Killeen’s hat to fall.

Previously hosting the Big Brother Australia series, Killeen has undergone a fashion transformation, keeping it all under her hat. The ex host has been off screen for two years, and since then has re- designed her image.

Killeen’s new hair do will be revealed at Logie Awards, the night of all Australian TV nights (not to mention fashion) which she will host.

The Logies provide an array of fashion displays, Killeen hoping her new image will set the bar high. Although hoping for a fashion do, rather than don’t, Killeen is going to extraordinary lengths to keep her new look under wraps.

She wants the Logies to be her catwalk to debut the new look, a source saying “She wants to use the Logies as the big reveal of her new look after being off the radar for so long”.

Here’s hoping her style is ‘catwalk’ ready.
