The pair attended amfAR's 23rd Cinema Against AIDS Gala in Cannes, France, on Thursday, where they stole the show thanks to their super chic looks. The 31-year-old "Teenage Dream" singer stunned in a show-stopping red, off-the-shoulder Marchesa gown, featuring laser-cut organza flowers on the bell sleeves and the train.
And if the eye-catching ombre lace dress wasn't amazing enough, Perry also accessorized with dazzling Harry Winston 23-carat cluster diamond chandelier earrings.
But it looks like Perry's intricate frock was hilariously giving her a little bit of trouble. "How am I supposed to walk down these fu**king stairs? I'd like both hands," the singer cracked as two handsome escorts came to her rescue by grabbing both of her hands.
Bloom, 39, cleaned up nicely himself, looking handsome in a suit and a black bow tie.
Perry performed at this year's star-studded amfAR gala, joining amfAR global campaign chairs Sharon Stone, Kevin Spacey, Milla Jovovich, Adrien Brody, Heidi Klum, Carine Roitfeld, and Harvey Weinstein at the event. While Perry and Bloom didn't pose on the red carpet together on Thursday, they did stick close to one another once inside the venue, where Perry was snapped clutching Bloom's hand.
So far, the couple hasn't been shy about showing major PDA in Cannes. Earlier this week, they cuddled up on a boat ride and had lunch with their famous pals, including Kate Hudson and Kate Moss. On Monday, the two were snapped kissing aboard Russian businessman Roman Abramovich's luxury yacht in the French Riviera.
Perry, of course, isn't the only one making headlines for her Cannes fashion. On Wednesday, model Bella Hadid barely avoided a wardrobe malfunction in a nearly-naked red Alexandre Vauthier dress at The Unknown Girl premiere -- which singer Rita Ora actually already wore almost two years earlier at the 2014 MTV Video Music Awards in Los Angeles.
