The couple posed alongside Sophie and Joe at the star-studded event for the Paris fashion house.
On Monday, the "Electric" singer and her fiancé spent time with their married friends and they posed alongside Sophie Turner and Joe Jonas at the Louis Vuitton Parfum event at the Fondation Louis Vuitton in Paris.
The couple were dressed head-to-toe in Louis Vuitton for the event where the fashion brand unveiled its latest fragrance line, Les Extraits Collection, created in collaboration with architect Frank Gehry and the Maison’s Master Perfumer Jacques Cavallier Belletrud.
Perry wore a silver purse to match the bedazzled dress and drop earrings to complete the look. Bloom topped his shirt and pants with a statement-making Louis Vuitton harness.
"@louisvuitton puts the LV in L💜VE," the American Idol judge captioned the photos of her and Bloom making their way to the event.
Bloom posted some of his own photos from the dinner, sharing a cute kiss with his bride-to-be.
"You me n LV ❤️," he wrote next to the sweet snaps.
A source tells ET, "Katy and Orlando have been doing amazing as a couple and are so in love. They are so committed to being parents and are having the best time."
"Friends would not be surprised if they elope soon," the source says, adding that the pair "have been discussing marriage plans."
Amid these discussions, the pair have been on a tour of Europe, most recently stopping in Turkey. Perry shared some sweet photos of the couple at an infinity pool while at a resort in the city of Kaplankaya.
"Infinity & beyond ♥️," she captioned the set of photos, the first showing her and the Carnival Row actor sharing a kiss, and the second shows the happy parents smiling while standing arm-in-arm.
Last month, the pair were spotted packing on the PDA in Venice, Italy during the first leg of their European vacation.
Though they were seen traveling with their 10-month-old daughter and their dog, the pair did enjoy some solo time, snapping a kissing selfie and going for a romantic gondola ride complete with Aperol spritzes and even more smooches.
