The Anywhere singer looked stunning in her skimpy outfit as she enjoyed an evening at the BYREDO Eyes Closed Dinner in London.
Rita sported a smoky eye look and glam makeup and wore her dark blonde locks down to one side.
The 31-year-old strutted her stuff in sparkly black platform heels and put her gym-honed, tanned figure on display in the cut-out dress.
The star accessorised with some long earrings and a metallic silver clutch for the evening out.
Rita has recently returned to London after a trip to Auckland in Australia, where she performed at the Women’s Rugby World Cup.
