Dannii Minogue is the SPITTING image of her sister Kylie with new hairstyle

The 45-year-old has undergone a serious makeover.

From years of seeing Dannii Minogue on our screens on X Factor or as a judge on new BBC One show Let It Shine, we recognise Dannii for her big, beautiful blue eyes and her trademark dark, brunette coloured hair.

As she’s admitted in the past, she’s always compared to her sister Kylie so her choice as staying a brunette babe can be totally understood.

Taking to Instagram, Dannii may well be a convert of thinking “new hair, new me” as the singer took to Instagram to show her serious change from dark brown to a warm blonde colour.

Colour Transformation in the works… and oops I just discovered time lapse #colourtransformation

Keeping her trademark roots dark, Dannii debuted her new glossy mane with a much-lightened colour, making her a real blonde bombshell.

It’s a real change for the traditionally dark haired Dannii, that’s for sure.
