The 32-year-old former "X Factor" judge and Payne had their arms wrapped tightly around each other as they posed for pictures on the red carpet ahead of Eva Longoria's Global Gift Gala in Paris, reported Daily Mirror.
Cheryl stunned in a powder pink gown, which featured cut-out details on the waist.
Meanwhile, 22-year-old Payne was looking sharp in a simple black Hackett tux, although he went without a bow-tie for the glitzy bash.
