Leave it to Prince Harry to turn a cute selfie into a royal photobomb moment.
The 31-year-old was snapped making a funny face all while "America's Next Top Model" star Winnie Harlow was attempting to pose for a photo with her agent during the Audi Polo Challenge on Saturday.
"When you're trying to have a serious convo but your agent and Prince Harry aren't serious at all," the 21-year-old beauty wrote alongside the hilarious Instagram shot.
And in another (slightly more serious) Instagram, Harlow posted a photo of both Prince Harry and Prince William in the background during the luncheon.
"Canadian girl on British territory (how did this photog get Prince Will & Harry in this shot!? Very cool," Harlow posted.
Later on in the day, Prince William was seen greeting guests of the swanky event and even participating in a round of yoga on the lawn.
But when all eyes weren't on the father-of-two doing the downward dog in white chinos, attendees mingled with several famous faces including Mad Max: Fury Road's Tom Hardy, his wife Charlotte Riley and award-winning singer Ellie Goulding.
