Britney Spears calls her little sis Jamie Lynn a 'scum person' "You've stooped to a whole new level"

“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 !!!!”

Jamie Lynn Spears opened up to Juju Chang in an interview on ABC's "Good Morning America about her strained relationship with big sister Britney Spears.

Jamie Lynn told Juju Chang that Britney has often exhibited "erratic, paranoid and spiraling" behavior, recounting a time when her older sister once became "scared," took out a knife, and locked the two of them in a room.

"It's important to remember that I was a kid in that moment," Jamie Lynn said. "I was scared. That was an experience I had, but I also was fearful to really say anything because I didn't want to upset anybody — but also was so upset that she didn't feel safe."

Lil' sis spends a lot of time on social media posts and in this interview defending herself and making herself sound like a poor little innocent mistreated sister.

We're not buying that, but okay. Also wouldn't the real interview right now be to get one with Britney Spears herself?!

Oh well anyway watch Jamie Lynn's interview below:

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.

“I’ve never been around you ever with a knife or would I ever even think to do such !!!” Britney, 40, wrote in a statement posted to her Twitter Friday, adding, “The only knife I ever saw you with at home was cutting the biggest pieces of squash I ever saw in my life and it was way too big for me to cut.”

Here's Britney's Twitter post

Since June — when Britney first spoke out in court against her long-held conservatorship, which was terminated by a judge in November after 13 years — fans of the superstar have attacked Jamie Lynn online, accusing her of not supporting Britney during the conservatorship; she's even gotten death threats. Last week, Britney unfollowed Jamie Lynn on Instagram. (Jamie Lynn still follows her sister.)
