The video was shot in Valencia, Calif., this afternoon on a film set where Britney's younger sister Jamie Lynn is working. There are reports circulating that the papers are a restraining order, but TMZ has confirmed that is NOT the case. It is a letter from an out-of-state lawyer. By the way, Britney could not legally serve her mom with a restraining order if she was the one seeking it.
Sources say Britney feels that her mom turned on her in the days before she entered Promises rehab. She also feels Lynne Spears is not stable enough to be around Brit's kids because she may have her own "issues." We're told the letter bluntly asks Lynne to stay away from the children if she is taking any medications that would impair her ability to be around them.
We're also told Spears has become super-protective of her kids and is taking back a lot of the control that others were exercising over her life.
