Boyzone singer Ronan and his model girlfriend Storm were pictured arriving at Gabrielle's Gala, held in London to raise money for research into cancer.
The couple looked picture perfect in black and white, with Ronan opting for a smart suit and skinny black tie.
Storm, meanwhile, showed off her slender figure in a white satin cropped top and unusual black midi skirt, which featured a dramatic slit up the front.
The Australian star completed her outfit - by Aussie designer Manning Cartell - with chunky monochrome sandals and delicate drop earrings.
The event was held in Old Billingsgate by the charity Gabrielle's Angels and Rita Ora was also there on the night to perform for guests.
Before walking the red carpet, Ronan tweeted a photograph of Storm walking through their hotel reception with a dress bag over her shoulder.
Alongside it, the Irish singer told his followers: "Looking forward to tonight's @CureCancerNow Ball @StormUechtritz lugged @MANNING_CARTELL all the way from Oz for it."
