The former X Factor judge oozed sophistication in head-to-toe electric blue while attending an event to launch the new eBay Collections.
Gorgeous Dannii - who touched down in London yesterday - opted for a skin-tight Hervé Léger bandage frock, which highlighted her teeny tiny waistline.
In keeping with the blue theme, the Aussie starlet added a pair of vibrant courts with gold stiletto heels by Kurt Geiger.
She even gave us a close-up snap of her fabulous footwear, and we have to say, we love them!
And Dannii packed a punch on the beauty front too, sweeping her brunette locks into a side parting before tonging into loose curls.
She kept her make-up simple with defined brows, lashings of mascara and a slick of clear lipgloss.
The petite singer was joined by TV presenter Reggie Yates, Blur bassist Alex James and interior designer Kelly Hoppen MBE at the event.
Dannii's sister Kylie is also back in the UK at the moment as she's currently appearing as a mentor on The Voice UK.
We wonder if a family night out could be on the horizon? Fingers crossed - we'd love to see their outfits!
