A fan site for the actor has posted photos of what appears to be his wedding to fellow British thespian Laura Haddock.
The duo are seen sweetly cutting a multi-tiered cake as guests look on. In another photo they are shown in an alluring, intimate embrace.
Haddock, 27, who has a lead role on the Starz show Da Vinci's Demons, is seen wearing a white lace dress cinched above the waist with a band of sparkly silver, her hair romantically pulled back with the help of a silvery headband.
Claflin, 27, who will star as Finnick Odair in The Hunger Games: Catching Fire when it is released in November, dons a suit and loose tie.
The pair has generally kept mum about their relationship, but Claflin couldn't contain his excitement on Twitter about reuniting with her last May in their native land.
"Back in London and reunited with @laurajhaddock," he wrote. "Happy happy happy."
A rep for the actor did not reply to PEOPLE's request for comment.
