Lauren Bosworth: Samsung Sexy

Taking a break from her usual reality TV gig, Lauren ‘Lo’ Bosworth was spotted hosting the Verizon Wireless Samsung Rogue launch party last night (October 26).

The “Hills” babe looked lovely as she posed for the paparazzi outside Jet nightclub at the Mirage Hotel and Casino in Las Vegas.

A source told press that what started as a joke on the red carpet was quickly put to rest as Miss Conrad is teaming up with writers and producers, and it looks like they’re going for more serious actors with film experience.
