Socialite Paris Hilton has revealed that her zodiac sign, Aquarius, has some kind of cosmic link to the German physicist Albert Einstein. Einstein, according to the calendar, was a Pisces and not an Aquarian, reported Us magazine. "We are social butterflies, humanitarians, geniuses: Einstein was one," she said. The 'Come Alive' singer, 33, says she has developed a thick skin over the years, with friends as well as strangers. "So many people have bad intentions, so many girls want to hang out to be someone. I weed those people out of my life. I call them hungry tigers," she said. She also feels guilty about her famous sex tape with then-boyfriend Rick Salomon, which went viral in 2004. "It was devastating because that was someone I was with for a few years. I don't think I'll ever be able to fully trust any man again after that. It was just the most hurtful and awful thing that anyone could do to a little girl. I was very young, it wasn't my fault."
