Reza Pahlavi (Persian: رضا پهلوی)( born 31 October 1960) is the oldest son of Mohammad Reza Pahlavi, the last Shah of Iran, and his 3rd wife Farah Diba. Prior to the Iranian Revolution in 1979, he was the crown prince and the last heir apparent to the throne of the Imperial State of Iran. According to a People article published in 1978, Pahlavi dated a "blond, blue-eyed Swedish model he met in Rome". The same publication also reported that he lived with his girlfriend while living in Lubbock, Texas. As of 1980, he had an Egyptian girlfriend who was a student of The American University in Cairo, reportedly "closely guarded" by bodyguards.Pahlavi began a relationship with Yasmine Etemad-Amini in 1985, and a year later married her, then aged 17, at 25 years of age.

Ali Reza Pahlavi (Persian: علیرضا پهلوی) (28 April 1966 – 4 January 2011) was a member of the Pahlavi Imperial Family of the Imperial State of Iran. He was the younger son of Mohammad Reza Pahlavi, the former Shah of Iran and his third wife Farah Diba. He was second in order of succession to the Iranian throne before the Iranian Revolution. He was engaged in 2001 to Sarah Tabatabai, but it seems that the relationship ended some time afterwards. From 2008-2010 he was in a relationship with Sherene Melania. He was once voted as one of the "world's most eligible princes." After a long period of depression, on 4 January 2011 Pahlavi died in his apartment in Boston (Back Bay, 141 West Newton Street) from a self-inflicted gunshot wound. Mahnaz Afkhami, the former Iranian Minister of Women's Affairs of the Shah's government, told the BBC World Service that Pahlavi and his family being forced into exile in 1979 was very "traumatic" for him and that he had experienced a "loss of identity" in exile.https://en.wikipedia.org/..._Reza_Pahlavi_(born_1966)
