Queen Elizabeth and Prince Philip have been married for a whopping 68 years, and it seems like the love is as strong as it was on day one. The British royals released a new portrait taken by Annie Leibovitz at Windsor Castle to celebrate both the Queen’s 90th birthday party and Prince Philip’s 95th.

The monarch’s social media team released the new portrait with a quote from the Queen about her beloved husband, the Duke of Edinburgh: “He has, quite simply, been my strength and stay all these years.” It’s the latest in a series of photos released by the royal family in anticipation of the big birthday party. Leibovitz also took photos of the Queen with her daughter, Princess Anne, her great-grandchildren and youngest grandchildren, and her beloved corgis.

The Queen officially turned 90 in April, is the longest-serving British monarch ever, and is also the oldest one on the throne. And the couple is also the longest-married royal one in history. The celebration is already drawing in the rest of the royal family, including Prince William, Prince Harry, and Duchess Kate.
