There's been a misconception, the younger Spears said, about her role in Britney Spears' 13-year court-ordered conservatorship, which ended last year after a judge removed the pair's father, Jamie Spears, from oversight of her finances and medical decisions.

"When (the conservatorship) was put into place, I was (a) 17-year-old, I was about to have a baby," Jamie Lynn Spears, 30, told Juju Chang on ABC's "Good Morning America." "I didn't understand what was happening nor was I focused on that.

...

I understand just as little about it then as I do now."

"There was no me overseeing funds or something like that, and if there was (that perception), that was a misunderstanding, but either way I took no steps to be a part of it."

Jamie Lynn Spears even went as far as to help Britney Spears, now 40, explore options to get out of the conservatorship, said the actress and singer who rose to fame on the hit Nickelodeon show, "Zoey 101," and is now promoting her new book, "Things I Should Have Said."

"I've always been my sister's biggest supporter," Jamie Lynn Spears told "GMA." "So, when she needed help, I set up ways to do so, went out of my way to make sure that she had the contacts she needed to possibly go ahead and end this conservatorship and just end this all for our family.
