By choosing to marry a "commoner," Peter Jensen, an American she met while attending MIT, Princess Ubolratana was forced to give up her royal status, according to The Guardian.
Although the pair divorced in 2001, Ubolratana still isn't allowed HRH status — but instead goes by "Tunkramom Ying," which translates to "Daughter to the Queen Regent," the publication reports.
The ex-royal embarked on an acting career after returning to Thailand in 2001, starring in Thai films "Where The Miracle Happens" (2008), "My Best Bodyguard" (2010), and "Together" (2012), according to IMDb.
