Former X Factor judge Nicole, 35, looked breathtaking in a floor-length strapless black gown that showed off her incredible figure to full effect.
No wonder Lewis looks so happy!
The stylish twosome hit the red carpet at the amfAR Cinema Against Aids 2014 Gala in Cannes on Thursday night (22 May).
It was Nicole and Lewis' first red carpet appearance together this year – and since they rekindled their on-off relationship (again!)
The reignited their romance over Christmas, after previously splitting in June, and seem to be happier than ever. Lewis even referred to Nicole as his "wifey" in the caption for a Valentine's Day selfie taken at the Sistine Chapel.
But they aren't planning to wed just yet. In March it was rumoured the couple had become engaged but Lewis quickly shot the suggestion down. A source later said they were just enjoying getting to know each other again without worrying about the pressure of a wedding.
