She relinquished her royal title and settled in the United States with her husband, Peter Ladd Jensen, but came back to Thailand after divorcing in 1998.

Princess Bajrakitiyabha of Thailand

Princess Bajrakitiyabha of Thailand (Literally: “Princess Bajrakitiyabha, the Royal Granddaughter”), or known as Princess Pa, was born on 7 December 1978. She is the first grandchild of King Bhumibol and Queen Sirikit of Thailand, and the only child of Crown Prince Maha Vajralongkorn with Princess Soamsavali.

Princess Soamsawali of Thailand

Phra Chao Worawong Thoe Phra Ong Chao Soamsawali Phra Worarachathinatdamat (Literal: “Soamsawali, the Princess Mother of the King’s First Grandchild”), or Soamsawali, the Princess of Thailand, (born Mom Luang Soamsawali Kitiyakara) is a member of Thai Royal Family, and is the former wife of her first cousin, Crown Prince Maha Vajiralongkorn. She was titled “the Princess Mother of the King’s First Grandchild” after her divorce with the Crown Prince in 1991. She is also niece of Queen Sirikit.

Vajiralongkorn of Thailand

Somdet Phra Boromma-orasathirat Chao Fa Maha Vajiralongkorn Sayammakutratchakuman Literally: “Prince Maha Vajiralongkorn, the Royal Son and Crown Prince of Siam”) (born July 28, 1952)[1] is the only son of Bhumibol Adulyadej, the King of Thailand, and Queen Sirikit. He is currently crown prince of Thailand, and the heir apparent to the throne.

On January 3, 1977 Vajiralongkorn married Princess Soamsavali Kitiyakara (born 1957), a first cousin on his mother’s side. They had one daughter, Princess Bajrakitiyabha in 1978. Crown Prince Vajiralongkorn started living with actress Yuvadhida Polpraserth in the late 1970s and had several children with her. Although Princess Soamsavali had refused divorce for many years, Vajiralongkorn was finally able to sue for divorce in the Family Court in January 1993. In the court proceedings, Vajiralongkorn accused Princess Soamsavali of being completely at fault for the failed relationship. She was not able to refute the charges due to the prohibition against lèse majesté. The divorce was finalized in July 1993. Princess Soamsavali and her daughter continue to play a significant role in royal ceremonies.

When Vajiralongkorn was introduced to Yuvadhida Polpraserth, she was an aspiring actress. She became his steady companion and gave birth to his first son, Prince Juthavachara Mahidol, on 29 August 1979. He later had three other sons and a daughter by her. They were married at a palace ceremony in February 1994, where they were blessed by the King and the Princess Mother, but not by the Queen. After the marriage, she was allowed to change her name to Mom Sujarinee Mahidol na Ayudhaya, signifying she was a commoner married to a royal.

Vajiralongkorn married again, on February 10, 2001, to Srirasmi Akharaphongpreecha, a commoner from an otherwise modest background who had been in his service since 1992. The marriage was not disclosed to the public until early 2005. She gave birth to a son, Prince Dipangkorn Rasmijoti, on April 29, 2005 and was elevated to become Princess Srirasmi, Mom Srirasmi Mahidol na Ayuthaya. The son was immediately elevated to the rank of Prince.
