Prince Harry was caught out hilariously photobombing former America's Next Top Model contestant Winnie Harlow as she enjoyed lunch with her agent. Prince Harry and Prince William were sat on tables behind the model and were accidentally snapped, but not before the cheekiest member of the royal family stuck out his tongue for the photo.
Winnie shared the photo of the prince sticking his tongue out after noticing the camera, captioning the post: "When you're trying to have a serious convo but your agent and Prince Harry aren't serious at all."

Fans of the royal were quick to comment on the photo, with one person commenting: "That prince is so funny!" while another wrote: "He's the cool prince!"
In another snap, Prince William can also be seen at the back of the shot, although he is not paying attention to the camera while deep in conversation with a friend. Winnie wrote: " Canadian girl on British territory (how did this photog get Prince Will & Harry in this shot!? Very cool."

Prince Harry is unafraid to poke fun at himself and pull pranks, and most recently sent royal fans into a frenzy after ongoing Twitter banter with Barack and Michelle Obama in the build up to the Invictus Games saw him appear in a video with his grandmother, Queen Elizabeth. The queen rolls her eyes as Prince Harry shows her a video of the President's antics while the prince smirks at the camera and says "boom!" while imitating a mic drop.
The prince recently joined forces with Prince William to help raise money for the organisations they support as patrons by taking part in a series of polo matches. Since they began this tradition in 2007 the brothers have raised an incredible £9.5 million for charity.
