Sugarland’s Jennifer Nettles and Kristian Bush were both injured today during rehearsals for the duo’s upcoming 2009 tour. Nettles and Bush were running giddily across a Nashville-area athletic field in clear plastic globes, imitating the crowd-surfing portion of their show, when a sudden gust of wind sent their oversized hamster balls sailing toward each other at high speeds. The force of the ensuing collision sent both stars flying into the frontal walls of their respective globes. Nettles recovered admirably, leaping back up and mouthing “Whoops!” in the most adorable manner possible, while Bush remained curled up at the bottom of his globe with an inexplicably serene expression on his face. The two stars were escorted to a nearby hospital, where they were treated for minor injuries and released. They are expected to return to rehearsals tomorrow for the next phase of their training program, Goofy Dancing on Super Long Treadmills.
