Yes, we couldn't believe it either.
After years of an on-again/off-again relationship, the duo appeared as a united front at the Monte-Carlo Gala for the Global Ocean in Monaco on Wednesday.
Looking dapper in a black tux, Bloom, who's one of the event's chairs along with Madonna, Eva Longoria, Chris Tucker and Robin Thicke, looked proud standing next to his love for the world to see.
Perry seemed pretty smitten with the idea too, keeping it elegant in a nude dress with metallic silver sleeves. We've seen these two everywhere together ... on date night in London, sightseeing in Rome and even hanging with Pope Francis ... and now, finally making their red carpet debut as a couple.
Although the pair seemed to keep their hands to themselves, there's no denying those beaming smiles.
Perry and Bloom were also photographed with Prince Albert II of Monaco, Princess Charlene of Monaco.
The fundraising event raised money to support initiatives in favor of a sustainable ocean.
