Marilyn Monroe
Marilyn Monroe, born Norma Jeane Mortenson, didn't live a very lavish life until later on. She bounced between foster homes and orphanages for the entirety of her childhood. She wasn't even a natural blonde, she died her hair when she got older.
The Accidental Super Star
Monroe was working as a factory employee when a U.S. military photographer snapped a photo of her to test his film. That photo ended up being posted in a magazine, and Monroe's modeling life blossomed outward. She eventually died her hair straw-colored and became the "blonde bombshell" that everyone knows and loves.
