"There is concern for Mr. Brillembourg's well-being," the sheriff's department said.
Anyone who has seen Brillembourg or has information on his whereabouts is encouraged to call the sheriff's Homicide Bureau, Missing Persons Unit at 323-890-5500.
Princess Tatiana is a member of the former Greek royal family and the Danish royal family.
Last month, Princess Tatiana, and her husband, Prince Nikolaos, announced they were divorcing after 14 years of marriage. Prince Nikolaos is the son of Constantine II, who reigned as king of Greece until the monarchy was abolished in that country in 1973.
The Greek Royal Family announced their separation in a statement on their website last month.
Princess Tatiana, whose name is Tatiana Blatnik, is known as an entrepreneur, author and philanthropist.
She is also the founder of Breathe, a non-profit organization dedicated to raising awareness around mental health and building healthier, more compassionate communities.
