Royal party: The Queen, Will, Kate have Patron's Lunch

A day after Prince George and Princess Charlotte overwhelmed us with their cuteness, parents Will and Kate went out without the kids to continue the celebration for Queen Elizabeth II's 90th birthday.

The couple, in a car with Prince Harry, waved from a Range Rover behind the Queen and Prince Philip.

Also part of the parade: a bird who perfectly photo-bombed this picture:

After driving through The Mall in London, Will and Kate greeted some of the 10,000 guests who attended the celebratory Patron's Lunch. Queen Elizabeth II spoke at the gathering.

Despite the rain, attendees still seemed to have fun at the street party.

Following the event, Queen Elizabeth II heard about the news of the mass shootings across the pond. She shared a somber message on Twitter.
