King Willem-Alexander, Queen Máxima and Princess Catharina-Amalia of the Netherlands also confirmed their RSVP on their website.

Meanwhile, Queen Azizah of Malaysia recently told the Royal Watcher blog that she and her husband, King Abdullah, will be there.

The office of First Lady Dr. Jill Biden told the Associated Press she is going to the nuptials.

She confirmed the news herself on Monday, writing on Twitter, "I'm on my way to the Middle East and North Africa to build on our longstanding partnerships and meet with young people across the region to discuss how the next generation can thrive. I look forward to traveling to Amman, Jordan to join King Abdullah and Queen Rania in celebrating their son, Crown Prince Al Hussein's wedding to Ms. Rajwa Al Seif."

The Royal Hashemite Court revealed on Wednesday that 140 guests — including members of Jordan's royal family, other royals from around the world and heads of state — will attend Crown Prince Hussein and Rajwa's Islamic marriage ceremony at Zahran Palace.

Following the “elegant and understated” religious service, known as a “katb ktab,” the newlyweds will travel in a ceremonial Red Motorcade of Land Rovers and motorcycles to the reception at Al Husseiniya Palace.

In an interesting twist, the celebration will mark the second major royal reunion in just a few weeks.

On May 6, Crown Prince Frederik, Crown Princess Mary, Crown Princess Victoria, Crown Prince Haakon, King Philippe, King Willem-Alexander, Queen Máxima, King Abdullah and Queen Azizah all attended King Charles and Queen Camilla's historic coronation in London.

Though they weren’t at the church service at Westminster Abbey, Princess Elisabeth and Princess Catharina-Amalia — two future Queens! — attended the coronation eve reception at Buckingham Palace on May 5.

Crown Prince Hussein’s parents, Queen Rania and King Abdullah II of Jordan, were also royal guests at King Charles’ coronation, and the Queen of Jordan exclusively reflected to PEOPLE about what the experience was like.

“The ceremony was beautiful and unforgettable. It struck the perfect balance of solemnity, spectacle, and spirituality. The many different traditions and rituals we saw were a reminder of Britain's deep respect for its history, and the link between King Charles III and British sovereigns of centuries past. It is admirable to see how the British monarchy has evolved through the years and remained a steadying presence for the country and its people,” Queen Rania, 52, told PEOPLE.

“The coronation was, of course, steeped in tradition, but I was very impressed with how King Charles put his own stamp on the events. For example, it felt very natural to see representatives of different religions play a role in the service. This was unprecedented in Britain's history, but it showed how focused His Majesty is on inclusivity,” she added.
