Britney claims Jamie Lynn’s memoir is “at my expense”

She's not happy.

Britney Spears has accused her younger sister Jamie Lynn of promoting her new memoir "at my expense". Jamie Lynn appeared on Good Morning America earlier this week, insisting that she "took steps to help" end Britney's controversial conservatorship. Britney has now spoken out about what her sister said in the interview, saying the Zoey 101 actress "never had to work for anything" and that she had always been "the bigger person". Jamie Lynn has written her memoir, reflecting back on being a teen mom and the struggles she endured with her mental health in Things I Should Have Said. During the ABC interview, Jamie Lynn said she was always "my sister’s biggest supporter". But according to the pop singer on Twitter, that wasn't the case. She wrote: "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. "I wrote a lot of my songs and my sister was the baby. 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. "I do remember asking my sister why she did that when she knew I was waiting to change my show and her only words were "well, it wasn’t my idea’…" She added: "Hope your book does well Jamie Lynn". Britney's conservatorship was terminated in November after nearly 14 years which had allowed her father Jamie to have complete control over her life and finances.
