The famous blonde bombshell we all know and love was actually born Norma Jeane Mortenson, on June 1, 1926.

She lived with them until age 7 until sadly she was declared a ward of the state, and had to be taken in by her mother’s friend. However, this only lasted a few years. Monroe was sent to the Hollygrove orphanage in LA, and then a series of foster homes. before she was finally married off to a neighbor’s son at the age of 16 to avoid her being put back in the foster care cycle.
