Britney Spears and Jamie Lynn may not be all tat happy with mom these days.  According to a report from Star Magazine, Lynne Spears' daughters are crushed over her explosive tell-all, that the magazine claims will expose family's darkest secrets.  Star takes an exclusive look at the shocking book that dishes on everything from Britney Spears lesbian lovers to Lynne's scheme to take Jamie Lynn Spears baby.

The magazine reports that after all of the trials that Britney and Jamie Lynn Spears have been through lately (the unplanned teen pregnancy and the break downs from Britney) nothing has been worse than what their mother, Lynne, is about to do.  Star reports that she's set to publish a tell-all book under the guise of a memoir about raising her two famous daughters, Through the Storm:  A Real Story of Fame and Family in a Tabloid World.  "We're pushing for a September release," Curt Harding of Thomas Nelson books tells Star.

"They feel like they've been stabbed in the back by their own flesh and blood," one family friend tells Star.  "The two of them have enough problems in their lives without Lynne creating more.  She was there every step of the way, so she knows all of her daughters' dirty little secrets."

The magazine notes that Lynne knows all of the "dirty little secrets"  Says the friend:  "Lynne has loads of stories about Britney's out of control behavior."
