Queen Elizabeth II was chilling with Alan Titchmarch and his wife, Alison, in Windsor. Because that's how she rolls.
"ROUND UP ALL THE PARTICIPANTS OF THE ROYAL WINDSOR HORSE SHOW JUBILEE PAGEANT SO THAT I MAY WEAR A NICE POWDER BLUE DRESS AND PEARLS," she [probably] orders.
Unfortunately, QE2 appeared to be accessorising her stylish look with a death glare pointed firmly at gardener-turned-talk-show-host Titchmarsh. Was it something he said?
