She is officially styled Her Royal Highness Princess Chulabhorn, which corresponds to her full Thai title Somdet Phrachao Luk Thoe Chaofa Chulabhorn Valayalaksana Agrarajakumari (Thai: สมเด็จพระเจ้าลูกเธอ เจ้าฟ้าจุฬาภรณวลัยลักษณ์ อัครราชกุมารี).[1]

In 1981, Chulabhorn married Royal Thai Air Force Air Vice Marshal Virayudh Tishyasarin (Thai: วีระยุทธ ดิษยะศริน; rtgsWirayut Dityasarin), a commoner.
