Spears gets nothing but high marks, according to the producer, whose credits include videos for Madonna, Metallica, Faith Hill and ‘N Sync.

“On set,” says Isham of Spears, “she was very professional, excited to work and beautiful as always. I was impressed with her focus as she choreographed the dance herself. Her endurance was remarkable, as we had a long day.”
