Britney Spears and her sister Jamie Lynn have become engaged in a public dispute over a recent TV interview and the pair's past relationship. The Singer accused her younger sibling of using The Interview on Wednesday to promote her new book " at my expense". Britney said Jamie Lynn had " never had to work for anything" and The Family " love to pull me down and hurt me". Jamie Lynn said Britney 's statements were " Absolutely Not The Truth " and she was " always here" for her sister. The 30-year-old also said she had to explain to her children " why Our Family continues to get death threats, as a result of their aunt's vague and accusatory posts, especially when we know she could tell The Truth ". for The Way she was treated during a 13-year conservatorship, when her finances and lifestyle were controlled by father Jamie. The Arrangement was ended by a court. Britney 's sister gave an interview to ABC's Good Morning America earlier This Week to promote her memoir Things I Should Have Said. The Book reportedly details her own Life Story , including her young daughter's in 2017, her relationship with Britney and The Role she played in The Singer 's controversial conservatorship. During The Interview , Jamie Lynn described herself as " My Sister 's biggest supporter" and said she " took steps to help" end the conservatorship. But according to ABC, she also describes Britney 's past behaviour in The Book as " erratic" " paranoid" and " spiralling". She told the programme: " When [the conservatorship] was put into place I was 17 years old, I was about to have a baby, so I didn't understand what was happening, nor was I focused on that. " Jamie Lynn went on to suggest her sister had approached her to ask if she " would be the person who ensured her boys got what they needed" which she agreed to. But, she continued: " Once I realised that, 'you know what, she's in a conservatorship', I felt like I just didn't want to be a part of [it] until maybe she was out of the conservatorship. So There was no me overseeing funds or something like that, and if that was then it's a misunderstanding, but Either Way I took no steps to be a part of it. " , Britney said: " I looked at my phone and I see that My Sister did her interview to promote her book. " The two things that did bother me that My Sister said was how my behaviour was out of control. " She was never around me much 15 years ago at that Time . . so why are we even talking About That unless she wants to sell a book at my expense. " Britney also said she was still upset by Jamie Lynn previously performing remixes of her hit songs. " I know it may sound like a silly thing to Most People but I wrote a lot of My Songs and My Sister was The Baby , " the 40-year-old pop star wrote. " She never had to work for anything. Everything was always given to her. " I always was the bigger person. They all got to do it and Play Me and I always sat there and took it. " She added: " Hope your book does well Jamie Lynn. " Jamie Lynn Spears has now responded to Britney 's response, telling her Instagram followers: " Quite frankly, the things being said are Absolutely Not The Truth . " She Said her book is not solely about Britney , but added: " I can't help that I was born a Spears too, and that some of my experiences involve My Sister . " Jamie Lynn, who starred in the Nickelodeon TV shows All That and Zoey 101 and has released music of her own, referred to the " unhealthy chaos that has controlled My Life for so long". She wrote: " I've worked hard since before I was even a teenager, and I've built my career in spite of just being someone's Little Sister . " There are no sides, and I don't want drama, but I'm speaking my truth to heal my traumas, so I can close this chapter and move forward, and I wish My Sister could do the same. " Meanwhile, that Britney will sit down with Oprah Winfrey for a tell-all interview later this year. That has Not Yet been confirmed, but on Twitter her desire to be interviewed by Oprah .
