Kathie Hilton did a good job in raising her kids, as her number one daughter can testify all for herself. Apparently, the mother of the pop sensation (?) told her that performing oral sex on boys makes your face ugly and Paris certainly didn't want that to happen to her...

In the latest line of 'Believe or Not' interviews (after the 'I will not have sex for an entire year' one), the blonde Paris told TMZ that she was too scared to perform oral sex on boys because her mother had warned her against it. Until she was 19, the heiress refused to do such thing because Kathie had told her that craters would appear on her face.

The first one that convinced the air-head that such a story is complete bull was her boyfriend Rick Salomon, the man with whom the socialite stars in the infamous tape 'One Night In Paris', when she was only 19.

'My mom told me that you get those holes in your face, craters... from giving blow jobs. I totally believed her. She's like, "It's from sucking". I'm like, "Ewww!". I told my boyfriend - he's like, "Why don't you ever do that?" I'm like, "Because my mom told me you get these craters". And he's like, "Paris, you're 19. You're allowed to do this"', Paris said to a reporter.

And, as if that much wasn't enough about her sex life, she goes on to say exactly how many people she had performed fellatio on: 'I've only done that [fellatio] with maybe three people in my life'.
