Britney Spears denied she ever held a knife up to her “scum” younger sister, Jamie Lynn Spears, after the “Zoey 101” alum made the accusation in a TV interview while publicizing her upcoming book!

Britney then told Jamie Lynn, 30, to stop telling “crazy lies” just to sell her memoir, “Things I Should Have Said,” and called her out for allegedly making up stories about her.

Jamie Lynn claimed in an interview with ABC News earlier this week that Britney once locked them in a room while brandishing a knife.

“It’s important to remember that I was a kid in that moment,” Jamie Lynn said during the sit-down.

Jamie Lynn also claimed in the interview that she “went out of her way” help free her sister from a conservatorship, though Britney previously said the “Sweet Magnolias” star “did nothing.” The legal arrangement was terminated in November 2021 after 13 years

The pop star slammed her sister Thursday for her comments during the interview, tweeting that Jamie Lynn “never had to work for anything” and was lying about their relationship to sell her book

But Jamie Lynn defended her memoir, insisting it’s about her own life experiences and not her sister’s
