Because Now On MTV, Everyone Gets A Show!:

Basically, the show is supposed to be like The Hills. Whitney will be traveling coast-to-coast while working for her fashion PR firm that she landed while on The Hills.

I've talked trash on the Hills girls before. But I will be the first to admit, scripted or not, I watch The Hills like my life depends on it. They should have rehab for crappy reality tv, but they don't. So I will continue to watch my scripted reality shows imagining myself eating sushi with LC. Until that day comes, I doubt I will ever get over my addiction. Besides, they don't follow Whitney too much, so they got my attention.
