Paris Hilton is preparing to go on the road with her boyfriend Benji Madden's band Good Charlotte when the rockers kick off an international tour next week (begs17Mar08). The 27-year-old heiress has been with the guitarist - bandmate and twin brother of Nicole Richie's partner Joel - for just over a month, but she is convinced their new romance will be able to survive life on the road. She tells U.S. magazine People, "We're actually leaving in a couple days for South Africa, so I'll be with him. "I'm just happy to be together, so no matter where we are, we'll have a great time." After shows in Johannesburg and Cape Town, South Africa, the rockers are due to perform in Europe before hitting the road in North America in the summer (08).
