Jamie Lynn Spears Talks Emancipation, Britney on 'Call Her Daddy'

Jamie Lynn Spears says she was treated much like her older sister, Britney, was during her teenage pregnancy in the mid-2000s, and it got so bad ... she almost legally broke free.

The former Nickelodeon star dishes about attempts to seek emancipation from her parents in her memoir, "Things I Should Have Said," -- and she went into more detail about that dark period on the "Call Her Daddy" podcast.

According to JL, she actually hired lawyers and drafted up paperwork in her would-be bid for freedom at just 16 -- this after she claims her parents isolated her from the outside world, not to mention her then-BF Casey Aldridge ... upon learning she'd gotten pregnant.

Jamie describes her parents being super controlling amid her pregnancy, saying they completely cut her off from all outside communication ... fearing news of the pregnancy would leak. At the time, they were also dealing with Britney's very public breakdown.

Speaking of which, Jamie Lynn claims to have been mostly ignorant to what was going on with Brit ... acknowledging she was absorbed in her own drama and problems. When she finally had the kid -- against her parents' wishes, she alleges, and after the story had leaked -- Jamie says she continued being heavily monitored by her family, and realized she'd never be able to get out from under their collective thumbs ... unless she went to court.

Jamie Lynn says her mom, Lynne, was served emancipation papers, but in the end ... they struck a deal that allowed Jamie to buy her own home and be with her own new family unit.

There's more here about Britney's episodes too ... Jamie Lynn talks about how her mom would often fly out to go handle a Britney-related matter any time something came up, which she says became more and more frequent. Again, Jamie Lynn denies knowing details ... insisting her parents and the team at large kept everything on a need-to-know basis.

With that said, Jamie says she remembers exactly where she was when she learned Britney had shaved her head ... and it sounds like the whole saga hurt her little sis as well. She breaks down in tears recounting and processing everything ... and it obviously impacted her.

BTW, the recent back and forth bickering Jamie Lynn and Britney have been engaged in also gets addressed in this sit-down ... with JL providing what she claims is text message evidence to clear her name, something 'CHD' teased hard in their promo of the interview.
