This tribute is fit for royalty.

Prince William and Kate Middleton commemorated a significant marriage milestone by sharing a new family photo of themselves cuddled in the grass with their three children, Prince George, 12, Princess Charlotte, 10, and Prince Louis, 8.

In the snapshot, the family of five is lying in a meadow together, with George sandwiched between his parents while Kate has Louis and then Charlotte on her other side. The family is all smiling widely as they bask in the sun together.

Kate and William captioned the portrait, which was shared on their official Prince and Princess of Wales Instagram account on April 29, “Celebrating 15 years of marriage.” They capped off the post with a red heart.

Throughout their nearly two decades of marriage—which began at London’s Westminster Abbey in 2011—not only have William and Kate experienced the joys of parenthood, but they’ve also been each other’s biggest supporters as they’ve navigated life in the international spotlight.

This support was never more evident than when Kate was diagnosed with an undisclosed form of cancer in 2024.
