The photo shared on the princess’s Instagram page showed the pair standing under a cherry blossom tree surrounded by pink petals.
Princess Eugenie can be seen smiling while her husband appears to be shaking the branches of the tree to send the petals falling down onto the floor.
The caption reads: “Happy Valentine’s Day.”
It is the royal couple’s fourth Valentine’s Day together since they married at St George’s chapel in Windsor in October 2018.
The princess was spotted watching the Super Bowl alongside her cousin Prince Harry on Sunday night, leading some Instagram users to suggest she may still be in California.
