The former child actor was speaking with ABC News on Wednesday (12 January) when she made the comments.
In the interview, host Juju Chang noted that in Jamie Lynn’s memoir, Things I Should Have Said, she described Britney’s behaviour over her lifetime as “erratic, paranoid, and spiralling”.
In the book, Jamie Lynn also claimed that there was an incident where Britney became “scared” and took a knife and locked herself and Jamie Lynn inside a room.
When questioned by presenter Juju Chang on why she would share such a vulnerable moment of Britney’s in public, Jamie Lynn said: “First off, I think experiencing my own panic attacks and how sometimes we can feel in those moments is important. It’s important to remember that I was a kid in that moment. I was scared. That was an experience I had, but I also was fearful to like really say anything because I didn’t want to upset anybody but also was so upset that she didn’t feel safe.”
The Independent has contacted Britney’s representatives for comment.
In the interview, Jamie Lynn discusses other aspects of her strained relationship with Britney, whose conservatorship came to an end after 13 years in November.
The rift between the siblings became public during the final months of Britney’s legal battle to end her long-standing conservatorship.
In June last year, Britney broke her silence on the conservatorship in a court testimony during which she called for her father and others involved in the legal arrangement “to be in jail”.
Following her appearance at open court in Los Angeles, the singer wrote a lengthy message to fans in which she complained about people close to her “never showing up”.

The message came shortly after Jamie Lynn had publicly pledged her support for Britney for the first time.
In July, however, Britney called out her sister specifically.
“I don’t like that my sister showed up at an awards show and performed MY SONGS to remixes!” she wrote at the time. “My so-called support system hurt me deeply!”
She added: “If you’re like my family who says things like ‘sorry, you’re in a conservatorship’ ... probably thinking you’re different so they can f*** with you!”
The sisters’ mother, Lynne, has previously defended Jamie Lynn, telling critics to “stop” attacking her youngest daughter.
