Britney Spears Called Jamie Lynn "Scum" In A Scathing New Post And Denied The Allegation That She Locked Jamie Lynn And Herself In A Room With A Knife

On Wednesday, Jamie Lynn Spears appeared on Good Morning America to promote her new memoir, Things I Should Have Said.

According to the Daily Beast, the actor alleged that Britney Spears once locked them in a room with a knife. ABC News anchor Juju Chang asked why Jamie Lynn would share such a vulnerable moment of Britney's.

"It’s important to remember that I was a kid in that moment," Jamie Lynn responded. "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."

Britney already shared her scathing reaction to the interview as a whole. But today, the pop star responded specifically to the knife accusation, and she did not hold back, y'all.

"Jamie Lynn...congrats babe!" she wrote on Twitter. "You've stooped to a whole new level of LOW. I've never been around you ever with a knife or would I ever think to do such!"

"Please, please stop with these crazy lies for the Hollywood books! NOW and only NOW I do know only a scum person would make up such things about someone. I'm actually very confused about you making that up because it's honestly not like you at all!"

"Congrats on introducing your older sister [to] the concept of getting LOW...LOWER...LOWEST...because you win on that one, babe!" she concluded.

WHEW. You can read Britney's full statement below.
