Paris and Nicole hit the road

fter traumatizing parts of northwest Arkansas, Paris Hilton and Nicole Richie are taking on the rest of the country.

The socialites and best friends will spend the second season of their reality show, “The Simple Life,” on a road trip, Fox TV announced Monday.

“It’ll be interesting to see the country through their eyes,” Mike Darnell, Fox’s executive vice president of special programming, told the trade paper Variety. “Maybe Paris will visit a Wal-Mart. I’m kind of hoping they stop at a Hilton.”

Auditions for families to play host to Hilton and Richie will begin this weekend and are scheduled to last throughout the month; casting information is available on the Bunim-Murray Productions Web site. Production is expected to begin this spring, with the show airing later this year.

The first season of “The Simple Life” was a huge hit for Fox. It featured Hilton, the hotel heiress, and Richie, daughter of Lionel Richie, milking cows, washing trucks and shocking the locals while living with a family in rural Altus, Arkansas.
