Duchess of Cambridge Kate Middleton didn’t wear any old tiara to Queen Elizabeth‘s state banquet with U.S. president Donald Trump on Monday, June 3. Instead, she wore one of her most favorite headpieces — the Lover’s Knot tiara she sported at a Buckingham Palace reception party in 2015.

For the state banquet with Donald and Melania Trump, Kate paired her gorgeous crown with the Queen Mother’s sapphire, diamond fringe earrings and a blue, red and white sash of the Royal Victorian Order. She attended the event alongside her husband, Prince William, and they both looked stunning in their evening attire.

Kate, 37, wore a classic white Alexander McQueen gown while William, 36, got dressed up in a well-fitted tux. However, even though the two young royals arrived together, Kate and William weren’t seated next to each other. William sat next to Prime Minister Theresa May while Kate took her seat by the Lord Mayor of London, Peter Estlin.

In addition to Melania, four of Donald’s children — Ivanka, Donald Jr., Eric and Tiffany — attended the royal event in Buckingham Palace. The only one not in attendance was 13-year-old Barron, Donald’s only child with Melania.

After everyone took their seats, the U.S. president and the queen both made a speech about their respective countries and how they plan on keeping their alliance intact for the sake of their people.

“This evening, we thank God for the brave sons of the United Kingdom and the United States who defeated the Nazis and the Nazi regime and liberated millions from tyranny. The bond between our nations was forever sealed in that great crusade,” the queen said. Donald added, “Her majesty inspired her compatriots in that fight to support the troops, defend her homeland, and defeat the enemy at all cost.”

Donald and the queen are off to a great start for a wonderful friendship!
