Who knew royals could rock along with the best of them?
The best of them including one Sienna Miller...
The Concert For Diana, held at London's Wembley Stadium, was a royal rock fest of note.
And not just because Wills and Harry organised it, or because a handful of other royals, such as Zara Phillips, pitched up.
But also because the line-up included pop royalty like Duran Duran, Elton John, Lily Allen and Joss Stone.
A smiling Harry got things started on stage with the greeting: "Hello, Wembley."
And it wasn't just the acts that got Harry grinning.
He and girlfriend Chelsy Davy cuddled and chuckled throughout the show.
Meanwhile, there was much mystery surrounding Wills and his ex, Kate Middleton.
Kate was perched just rows behind Wills, but reports say they kept a safe distance from each other.
This all comes after rumours claiming they're dating again.
Guess we'll have to keep our peepers peeled to see whether or not the royal romance will be rekindled.
In the meantime, have a look at the rest of the royal action in our picture gallery...
