Heartwarming photos show the man, dressed smartly in a three-piece suit, down on one knee proposing to his female companion with paparazzi rushing to snap the couple.

Luckily for him, his partner appeared to say yes and they shared a passionate kiss in front of a crowd of people at the famous film festival.

The woman, in a glamorous floor-length red dress, looked overjoyed at the proposal, and smiling photographers appeared to enjoy the touching moment.

After sharing a passionate kiss, the happy couple walked off hand in hand, beaming smiles plastered on their faces.

The 72nd annual Cannes Film Festival is currently taking place from May 14 to May 25.

From Pamela Anderson to Dua Lipa, the great and good of the movie and music world mingled at the Cannes Film Festival's most glamorous fixture on Thursday night, a fundraiser for AIDS research where stars including Mariah Carey took to the stage.

Reality TV star and model Kendall Jenner, actors Antonio Banderas, Andie MacDowell and Pamela Anderson, and designer Tommy Hilfiger were among guests at the swanky AmfAR dinner on the French Riviera, put on by the U.S.-based Foundation for AIDS Research.

Attendees and AmfAR representatives said this year's event - which also featured crooner Tom Jones singing some of his hits including "Sex Bomb" - was particularly poignant, following medical breakthroughs in trying to find a cure for AIDS.
