Ronan Keating and new girlfriend Storm Uechtritz have made their first official public appearance together on the 'green' carpet.
Hosting the event, Keating looked absolutely delighted as he posed for photographs with his other half, who was dressed in a glamorous white, Grecian-style gown.
Although they have been pictured strolling arm-in-arm around the Australian city in recent weeks and at the Melbourne Cup, last night saw their debut outing on the red carpet at an official star-studded event.
As well as MC'ing the night, Keating (35) performed songs from his new solo album 'Fires' for guests.
Keating's Boyzone band mate is in Australia ahead of his appearance on reality series 'I'm A Celebrity Get Me Out of Here' next week, where he will join Irish host Laura Whitmore on a discussion panel.
All funds from the Emerald and Ivy Ball go towards the Cancer Council's Ronan Keating Fellowship, which is a three-year initiative aimed at reducing the impact of cancer on the community by covering prevention, screening, diagnosis, treatment, support and palliative care.
