Hardly anyone embodied the role of the latently stupid It girl as well as Paris Hilton. "Be smart, pretend stupid," is her unofficial motto, which has helped both Verona Pooth (formerly Feldbusch) and Daniela Katzenberger to fame in this country.

That Hilton is by no means stupid is shown by her ongoing success. Today, the mother of one child is an entrepreneur worth millions - and shows a different side of herself in her new autobiography "Paris". Among other things, she talks about her private sex film "One Night in Paris", which she shot in 2001 with her then boyfriend Rick Salomon. At that time, the hotel heiress was just 19 years old, her boyfriend 31.

Hilton said she had no power over the video. "The lighting would have been better," she writes. "I would have had the right hair, makeup and wardrobe. The camera angles and editing would have been more flattering," Paris said. She doesn't name her ex-partner in her book, but describes him as the "perfect man for a girl going through the most self-destructive moment of her life".

Salomon told her that "it was just for us, no one else would ever see it," reports the 42-year-old. "And then he told me that if I didn't do it, he could easily find someone who would, and that was the worst thing I could imagine - to be left by this grown man because I was a stupid kid was that didn't know how to play with adults."

Not the only traumatic experience with a man. In middle school, she and her friends fell in love with a handsome teacher. He, in turn, assured Hilton that he liked her too and asked her for her number. "He called me almost every night. We would talk for hours about how incredibly mature, beautiful and intelligent I was, how sensual, misunderstood and special," she says.

She tried to justify the big age difference to herself. "He reminded me that Princess Diana was thirteen years younger than Prince Charles. And Priscilla Presley was my age when Elvis fell in love with her," Paris writes, according to People. One evening when her parents were not at home, the teacher came to see her. "[He] pulled me into his arms and kissed me," she recalls. When her parents caught her, the teacher is said to have blamed her. "Why did you force me to do this?" he asked her.

Many years later, in her twenties, another low point plagued Hilton. She found out she was pregnant. "It was like waking up on the ledge in front of a fortieth floor window. I was scared and heartbroken," she writes. It was an "extremely private ordeal," said Hilton. She finally decided to have an abortion, which she does not regret today. "The only reason I'm speaking out now is because so many women are facing this and feeling so alone and judged and abandoned. I want them to know that they are not alone and don't owe anyone an explanation," explains she.

Today, Hilton is married to Carter Reum, and the wedding was followed by cameras. They recently announced that they had become parents to a boy. Phoenix Barron Hilton Reum was born thanks to a surrogate mother.
