William calls Kate the "arty one" amid photo scandal, as he and Harry keep their distance at Princess Diana event

London — Not even an event honoring the late Princess Diana could bring her estranged sons, Prince William and Prince Harry, back together this week. At the 25th annual Diana Legacy Awards, honoring young global change makers in London, the two brothers clearly kept their distance Thursday night — in both time, appearing hours apart, and in place, as they were half a world away from each other.

William, the Prince of Wales, attended in person and celebrated the 20 winners, whom he lauded as prime examples of "my mother's belief that young people can change the world."

"She taught me that everyone has the potential to give something back, that everyone in need deserves a supporting hand in life," William said of his late mother.
