Prince William, Kate make rare appearance at royal wedding in Jordan

First lady Jill Biden is also attending the wedding of Jordan's crown prince.

Just one month after celebrating their own 12th wedding anniversary, Prince William and Kate, the Princess of Wales, are making a rare appearance as guests at another royal wedding.

William and Kate traveled from their home in Windsor, England, to Jordan to attend the wedding of Crown Prince Al Hussein bin Abdullah II, 28, and Rajwa Alseif, 29, on Thursday.

The Waleses are reportedly among 1,700 guests at the high-profile wedding.

Kate was seen arriving in a pale pink dress, while William chose a dark suit and blue tie for the occasion.

William and Kate were not the only members of Britain's royal family to attend, as William's cousin, Princess Beatrice, and her husband, Edoardo Mapelli Mozzi, also attended the ceremony.

U.S. first lady Dr. Jill Biden was also in attendance at the royal wedding, held at Zahran Palace.

The bride and groom were both educated in the United States.

Alseif, who was born in Saudi Arabia, graduated in 2017 from Syracuse University, where she studied architecture, according to The Associated Press.

She also earned a degree in visual communications from the Fashion Institute of Design and Merchandising in Los Angeles, according to the AP.

The crown prince, the son of King Abdullah II, graduated in 2016 from Georgetown University with a degree in international history.

The next year, he graduated from the British Royal Military Academy in Sandhurst, according to the AP.
