Britney Spears has heated words for Jamie Lynn Spears.

On air, Jamie Lynn explained why she included a claim that Britney once took a knife and locked the two of them in a room together. According to Jamie Lynn, she was "scared" during the alleged incident and the resulting experience spoke to her "own panic attacks.".

In a statement released on Twitter, Britney responded to the allegation and said that Jamie Lynn "stooped to a whole new level of LOW.".

The pop star and her sibling have been engaged in a public war of words ever since Jamie Lynn's interview aired on Jan.

During the candid sit-down with Juju Chang, Jamie Lynn addressed her family's "complicated dynamics" and said that she "didn't understand what was happening" when Britney was placed in a conservatorship more than 13 years ago.

A day after Jamie Lynn's televised interview, Britney took to Twitter and said that some of her sister's comments "did bother me.".

Jamie Lynn later personally addressed Britney in a statement released earlier on Jan
