Britney Spears' sister Jamie Lynn calls public feud 'embarrassing', begs pop star: 'This has to stop'

Britney Spears' younger sister Jamie Lynn Spears has pleaded with the pop star to "just call her", dubbing the sibling's public feud "embarrassing" and insisting "this has to stop". 

The drama began when Jamie Lynn gave a candid interview on Good Morning America to promote her new memoir Things I Should Have Said, in which she broke down discussing the rift with her famous sister. 

It was also revealed Jamie Lynn had dubbed some of Britney's previous behavior as "erratic, paranoid and spiralling" in her book. 

Britney hit back, claiming Jamie Lynn "was never around her much" 15 years ago, adding she felt her sister wanted to "sell a book at her expense" and saying she was "disgusted" with her family who had "ruined her dreams".

"She never had to work for anything, everything was always given to her," Britney tweeted about her sister. 

Jamie Lynn responded on Instagram with a message accusing her sister of lying, telling her: "It's become exhausting when conversations and texts we have in private don't match what you post on social media." 

"I hate to burst my sister's bubble, but my book is not about her. I can't help that I was born a Spears too," she wrote. 

Jame Lynn insisted she would "always love" her big sister and would "be there for her".

"It's time to put an end to the unhealthy chaos that has controlled my life for so long," she concluded - but the situation only escalated from there. 

The following day, the 'Gimme More' singer furiously retaliated against allegations made in Jamie Lynn's book that claimed Britney once locked the two sisters in a room together and chased Jamie Lynn with a knife. 

Britney denied the accusation, calling her sister "scum" and telling her: "Congrats babe, you've stooped to a whole new level of LOW."

"I've never been around you ever with a knife or would I ever even think to do such!" she said. 

"Please stop with these crazy lies for the Hollywood books. Now and only now do I know only a scum person would make up such things." 

Around 24 hours later, Britney appeared to have softened slightly, telling Jamie Lynn in yet another message posted to Twitter: "I don't think your book is about me at all... I said some harsh things because you obviously hurt me by the things you are making up about me!" 

"I know you worked hard for the life you have and you have done amazing! But I think we would both have to agree to the fact that the family has never been remotely as hard on you as they have been on me!"

Referring to the 13-year-long conservatorship in which Britney's business, personal and financial affairs were controlled by her father, she declared: "What dad did to me, they don't even do that to criminals... so for you to sit back and act completely aloof to what has happened to me is honestly insane." 

"You guys treated me like nothing and that's not even half of it," she added. 

"I'm honestly shocked dad isn't in jail! Come on! We are supposed to have each other's back... but what you're saying just truly confuses me! All I know is I love you unconditionally!"

Seemingly attempting to put an end to the messy public back-and-forth, Jamie Lynn responded on Instagram, writing: "Britney - just call me." 

"I have attempted many times to speak to you directly and handle this privately like sisters should, but you still choose to do everything on a public platform.

"In the meantime, please stop continuing the narrative that I haven't been there for you or that I'm making things up," she added. 

"I'm happy to share how many times I've reached out to you, supported you and tried to help you. This is embarrassing and has to stop. Love you." 

Jamie Lynn is continuing to promote her upcoming memoir online and in the press.
