Molinari, the owner of Bootsy Bellows, shared the video on his Instagram page. "When [your] bassst Fran gives you the best birthday ever ?? #blessed @katyperry you are my legs ! ? forever," he wrote.
They were all celebrating at the Hotel du Cap-Eden-Roc, where the A-list pair graced us with their summer-ready bodies. Bloom, 37, was shirtless during the soiree, wearing just a gold chain and swim trunks, while Perry rocked a black bikini as she giddily sang and took video of the birthday cake on her phone.
The pair just made their relationship Instagram official when the 31-year-old singer shared a goofy snap of her and her beau sprawled out on the steps of a French hotel during a reprieve from the festival.
They were also spotted cuddling up during a boat ride and lunching with their famous pals, Kate Hudson and Kate Moss, and the two were seen kissing aboard Russian businessman Roman Abramavoch's luxury yacht in the French Riviera.
