Arnold Schwarzenegger's wife Maria Shriver has unwittingly inspired Kimberly Stewart's new clothing line.

Shriver, a member of America's high-profile Kennedy family, recently made a statement that stuck in Stewart's mind, and now the blonde beauty is including it in her planned line.

Stewart, daughter of rocker Rod Stewart, says, "We're making T-shirts with cute little sayings on them. One of them is 'Wellbehaved women never make history'.

"Maria Shriver said it, and thought it was cute because it's true."
