It’s hard to believe that Kylie Minogue is really 45 years old.

Last night, the actress/singer made a guest appearance on the Italian version of ‘X Factor’.

She performed tracks from her new ‘Abbey Road’ album during the live show, which was filmed at the famous Teatro della Luna in Milan, Italy.

Wearing a tiny Dolce & Gabbana Spring 2012 bejewelled one-piece, the star showed off her perfect pins but the look covered up her famous derriere.

Opting for more dazzle – and height – she styled the look with Christian Louboutin spiked ankle boots.

Taking us back in time, the Aussie star sported a super-curly bouffant à la Charlene Robinson in Neighbours.
