Paris Hilton is taking a break from her not-so-simple life to appear in the Feb. 2 episode of NBC's Las Vegas. And, in a shocking twist, the reluctant porn icon will not be playing herself. Instead, she'll appear as the fiancée of a Montecito high roller (90210's Brian A. Green, the real-life beau of Vegas star Vanessa Marcil). Still, as exec producer Gary Scott Thompson points out in next week's TV Guide magazine, "It's close to who she is and in the realm of what she can do... [but] tamer than some of the stuff she's getting press for." But, to ensure that she'd feel at-home, the entire episode was shot using a grainy, night-vision lens.
