Jamie Lynn, 30, shared a message onInstagramearly Friday insisting that she “is always here” for her older sister while explaining the accusations Britney, 40, posts on social media “don’t match” what is said between the sisters in private. She claimed Britney’s posts lead to “death threats” against her family.
“Brit, I am always here for you, you know behind the scenes I have always been here. It’s become exhausting when conversations, and texts we have in private don’t match what you post on social media,” Jamie Lynn wrote.
She added, “Quite frankly, the things being said are absolutely not the truth, and I have to clarify that, because now it’s getting harder for me to rationalize to my oldest daughter 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, and put an end to all of it in one second if she wanted to.”
Jamie Lynn also hit back against Britney’s claims that she was selling her new memoir,Things I Should Have Said, at her sister’s “expense.”
She wrote, “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, and that some of my experiences involve my sister. 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.”
Ending her statement, she wrote, “There are no sides, and I don’t want drama, but I’m speaking my truth to heal my trauma, so I can close this chapter and move forward, and I wish my sister could do the same. No matter what comes, I will always love my big sister, and be here for her. It’s time to put an end to the unhealthy chaos that has controlled my life for so long.”

Jamie Lynn has repeatedly insisted she supports Britney, while her older sister has denied her claims and previously accused her family of conservatorship abuse. Her father, Jamie; her mother, Lynne; and Jamie Lynn have all denied wrongdoing.
Britney said her conservatorship “killed” her “dreams” in a JulyInstagrampost, writing, “I don’t like that my sister showed up at an awards show and performed MY SONGS to remixes !!!!! My so-called support system hurt me deeply !!!!”
In June, Jamie Lynnappeared to supportBritney after the singer made astatementin court asking for her conservatorship to be terminated.
“Since the day I was born, I’ve only loved, adored and supported my sister. I mean this is my freaking big sister, before any of this bulls—,” Jamie Lynn said in a video shared to her Instagram Story.
She added, “I don’t care if she wants to run away to a rainforest and have [a] zillion babies in the middle of nowhere. This situation does not affect me either way, because I’m only her sister who’s only concerned about her happiness.”
In this week’s issue of PEOPLE, Jamie Lynn also said she’s “only ever tried to be helpful, so any notion that says the contrary is just completely ridiculous.”
For Jamie Lynn, “it was really important for me to separate myself from my family to focus on the familyI’vecreated, which is me, my husband and my daughters. Setting those boundaries in place was really important,” said theSweet Magnoliasactress, who is raising daughters Maddie, 13, and Ivey, 3, withhusband Jamie Watson, 40. “I am not my family. I am my own person. I fought very hard and worked very hard to establish myself and to build the life that I have today.”
