Prince Harry was in Colorado on Friday.
He went to a reception at a golf course in Sedalia while he was there.
Colorado Gov. Hickenlooper was at the reception.
And so was Olympic swimmer and gold medalist Missy Franklin.
It was actually her 18th birthday.
And Prince Harry and British Ambassador to the U.S. Sir Peter Westmacott helped sing "Happy Birthday" to her.
She was pretty stoked.
Here's video from the reception.
