However, fans are noticing two very important things about the photo.
The photo features Duchess Kate, Prince William, and Prince Harry running a race together. The photo is noticeably missing his wife, Meghan Markle.
“Wishing a very happy birthday to Prince Harry today!,” the royal couple wrote to Prince Harry.
Fans commented messages including, “Interesting photo selection! No Meghan…,” “The shade of them using this pic rather than one including his wife,” and more.
You can see the photo on their official Instagram account.
Back in August, Prince William and Kate Middleton did acknowledge Meghan Markle‘s birthday.
