President Joe Biden and first lady Jill Biden stopped by Windsor Castle on Sunday for tea with Queen Elizabeth.

The 95-year-old monarch wore a bright pink floral dress and matching hat when she greeted the Bidens at the dais in the Quadrangle of Windsor Castle.

Windsor Castle is a royal residence that sits around 20 miles outside of London and has belonged to the royal family for almost 1,000 years. Windsor Castle is where the Queen spent much of her time during the Covid-19 pandemic.

The Bidens were welcomed with a Guard of Honor military parade formed by the Queen's Company First Battalion Grenadier Guards, which played the American national anthem and gave a royal salute.

Biden and the Queen chatted outside for a bit before entering the castle for a private meeting.

Several world leaders gathered over the weekend for the Group of Seven summit, an organization of leaders who meet annually to discuss pressing issues on a global scale.

The Queen already met the Bidens on Friday when all three chatted at a Group of Seven summit reception. The meeting marked Biden's first time meeting the Queen since he was inaugurated in January. It's also the Queen's 13th meeting with a sitting US president.

Biden and the Queen previously met in 1982 when he was a US Senator, the Guardian reported.

"Joe and I are both looking forward to meeting the queen," Jill Biden told reporters when they arrived in Britain on Thursday. "That's an exciting part of the visit for us."

The Queen has continued her official duties after the death of her late husband, the Duke of Edinburgh. While at the Group of Seven summit, she caused laughter among world leaders during a photo-call.

"Are you supposed to be looking as if you're enjoying yourselves?" The Queen said.

She later drew even more amusement when she used a long ceremonial sword to cut a cake.
