Joe Biden was sworn in as the 46th President of the United States and Kamala Harris as Vice President on Wednesday this week. As part of the day, they visited the Arlington National Cemetery in Virginia, where they were joined by former presidents Barack Obama, George W. Bush, and Bill Clinton in commemorating fallen soldiers.

Prince Harry picture spotted at Joe Biden's inauguration

Prince Harry was also seen at President Biden's inauguration—but not as a conventional attendee of the event. Rather, when Biden spoke to Clinton in a hall at the cemetery, a photograph of the Duke of Sussex was spotted in the background.

In the picture, Prince Harry is seen in his military uniform. It was taken in May 2013, when the Duke laid a wreath at the Tomb of the Unknown Soldier at the National Cemetery in Arlington during a visit to the U.S. Biden and his wife Jill also attended the 2013 event. 

Fans noticed the Royal "cameo" on Wednesday and, once again, Harry's connection to the Bidens was revisited. The now President and First Lady have been friends with Prince Harry since the 2013 tour of the U.S. Reportedly, Queen Elizabeth II also sent a message to the new President, congratulating him ahead of Wednesday's inauguration.
