Besides the usual tech geeks gathered at the annual Consumer Electronics Show in Las Vegas and the adult films fans congregated at the 2009 Adult Entertainment Expo, a troop of celebrities have traveled to Sin City to take part in the presentation of some of the latest and coolest gadgets and products and to attend some of the sexiest and wildest parties in Vegas.

One of the most distinguished celebrities at the 2009 Consumer Electronic Show was the Academy-Award winning actor Tom Hanks, who contributed in Sony's demonstration of its new prototype eyeglasses with built-in video screens.  Award winning singer and composer Stevie Wonder also attended the 2009 CES to visit the National Federation of the Blind and Sendero Group's exhibit and to present the award for Best of Innovations Award at a reception ceremony sponsored by iBiquity Digital.

Other celebrities spotted at the 2009 CES include Jeopardy! host Alex Trebec, baseball legend  Reggie Jackson, music celebrities Usher, Ludacris, Will.I.Am, Akon and Soulja Boy as well as the NBC news anchor Brian Williams, who recorded several of his news broadcasts at the NBC Universal floor.

But while thousands of hardcore technology and electronics fans are attending the Consumer Electronics Show in Las Vegas this week, the Adult Entertainment Expo held at the SandsExpoConvention Center in the Venetian Resort and Casino and the 2009 AVN Awards are also bringing some of the hottest celebrities in the adult industry to town. The adult-oriented trade show and award ceremony congregated actresses such as Tera Patrick, Jenna Jameson, Bree Olson, Stormy Daniel, Jesse Jane, Eva Angelina and Mikayla Mendez, who traveled to Las Vegas to meet fans, sign autographs and pose for photos before attending a series of exclusive parties programmed before the AVN award ceremony, including Hustler’s Lingerie Party at Lavo, and the official AVN party at LAX in the Luxor Las Vegas.

Actresses Jenna Haze and Belladona will co-host the 2009 AVN awards ceremony held at the Mandalay Bay Resort and Casino, in where performers, directors and producers will be recognized over 100 different sex categories. Howard Stern’s comic Bubba the Love Sponge, King porn performer Ron Jeremy, UFC fighter Tito Ortiz and rocker Dave Navarro are also expected to attend the weekend festivities.
