NYDN got their hands on some exclusive pics of Brit from the video shoot that followed the now infamous OK mag meltdown.

Wearing little more than fishnet stockings and a minuscule black leather vest, Spears flaunted her bod to her new track "Get Back." But although she had shed her clothes, the 25-year-old mother of two could not shake her troubles. Spears appeared "disoriented" and "erratic" after one of many toilet breaks, sources said.

"You could see she was getting a bit wobbly, but no one expected her to throw a complete fit," a source told the British tabloid News of the World. "Suddenly, she was in floods of tears and stormed off set. She eventually came back but was sobbing hysterically."

With Spears in tears, the video's director had to call the shoot early and send everyone home, the newspaper reported.
