Prince Constantine-Alexios of Greece and Denmark has sparked romance rumors with a few notable names in Hollywood. The Greece native is a member of the former Greek royal family, born as the eldest son of Crown Prince Pavlos and Crown Princess Marie-Chantal of Greece. Constantine-Alexios' family ruled Greece until the country's monarchy was abolished in 1973. They officially received Greek citizenship in December 2024. (His family relocated to New York City in 2017.) Despite his family's history in Greece, Constantine-Alexios is known in the United States - partly due to his love life.
