Britney started off by apologising to Jamie Lynn for previously calling her "scum" before calling her out for spreading lies about her. "It's like you're going out of your way to lie about me and make me look bad 💔 !!! And if I wasn't your sister I would believe everything you're saying in your interviews … you're actually believable !!! It's scary 😱 !!!" Britney wrote.
The singer then referenced a time when Jamie Lynn and their dad were allegedly poking at her broken foot, adding, "I felt ganged up on so I said 'shut the f*ck up !!!' I never stick up for myself, so you were shocked !!!" Britney also brought up how Jamie Lynn reportedly never let her hold "the baby." "You would just yank her out of my arms !!!! You acted like you owned that household and I'm sorry you were too much," Britney wrote. "I know dad has taken a back seat because he doesn't do the conservatorship anymore so I guess you're feeling that your little sassy ass can boss them around, but I'm here as your older sister to keep it real with you and put you in your place !!!"
She continued, "You have the right to tell your story but honestly the timing … right when people are just counting down the the seconds until I do something wrong, you come out and literally say hurtful things about me lying … that's being so unsupportive and it's kind of insane … I'm honestly wondering if this is all a joke and you're testing me because this is so far from you it's not even funny … 💔😔."
