On the X Factor tonight Dannii Minogue let her hair down after a few weeks of sporting elegant updo’s.

As you know I’m not really a fan of her ombre hair and tonight her hairstyle made her look like medusa.

She arrived on stage wearing a black Halston Spring 2011 plunging halter gown with a draped skirt.

The sleek black dress was accented with a gold waistband and a red HIV Awareness pin.

I loved everything about this look excluding the hair.

Dannii accessorized with Talisman Gallery earrings and Charlotte Olympia heels.
