Britney Spears has been digitally altered to look slimmer in her latest video.
The 26-year-old singer appears noticeably more toned and trim in the final promo for her latest single "Piece of Me", in stark contrast to a leaked unedited version of the video which appeared on the internet earlier this month.
The promo, which cost around $500,000, features Britney and a group of look-a-likes evading the paparazzi by wearing matching wigs and storming a Hollywood club.
Despite having gained some weight since her chart-topping glory days, director Wayne Isham insists Britney was as "beautiful" as ever on set.
He said, "On set 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."
Wayne - who also directed Britney's "I'm Not a Girl, Not Yet a Woman" video - added the star's stamina was "amazing".
He said, "She almost outlasted me, which is amazing! It was a pleasure to work with her again."
