Paris Hilton's Surrogate Rule: A Smart Idea.

Paris Hilton encouraged her son's surrogate to watch episodes of The Simple Life while pregnant so that the fetus would get used to the sound of Hilton's voice. This is because unborn babies can hear sounds outside the body around 27 to 29 weeks pregnant and may even recognize certain sounds and voices with repetition. Hilton's son's favorite lullaby is her song, "Stars Are Blind."
