Reality TV couple JESSICA SIMPSON and NICK LACHEY are urging BRITNEY SPEARS to think twice about jetting off to Fijian paradise Turtle Island on honeymoon, because they had an awful time there. The pop stars, whose show NEWLYWEDS: NICK AND JESSICA has become a huge hit in America, spent their honeymoon on the tranquil island, but insist it's not the romantic hotspot it's made out to be. Lachey says, "They specialize in very large roaches that fly around your room and land on you. "But Britney and new husband KEVIN FEDERLINE are more impressed with the island's remoteness - the only way to get there is by boat and the paradise has a no-fly zone policy, forbidding planes and helicopters to shatter holiday-makers' peace and quiet.
