With her platinum blonde hair and signature red lipstick, Marilyn Monroe (who would have celebrated her 91st birthday on the 1st of June) is easily one of the most iconic celebrities of all time, however, only a few know what the actress looked like before she was famous. Born Norma Jeane Mortenson, Monroe had a really tough childhood. She moved from one foster home to another, going through traumatic experiences in almost all of them.
