Paris Hilton's found a new pop singer's daughter for her Simple Life escapades, USA Today reports. Rod Stewart's daughter Kimberly will slum it with the heiress in Maui for the fourth installment of the Fox show. Hilton told reporters she wanted the change to make the fourth season "funner." Meanwhile, ousted sidekick Nicole Richie's still on contract with the network, leading to speculation that she'll get her own reality show with fianc&#233 Adam Goldstein.
