A new pack of C-level celebs is in hot pursuit of their own reality shows. Star Jones wants one. (Guess she can moonlight while doing her Court TV show!) So does Bobby Brown. What’s more surprising is who’s not interested: Paris Hilton. The heiress’s contract on The Simple Life expires this month, and she’s not looking for another go-around. There’s still interest in her Life partner, though. One insider says Nicole Richie has been approached about doing a reality show about her pregnancy, but she’s not interested. Yet.
