Britney Spears 'Sorry' She Wasn't Strong Enough... To Slap Jamie Lynn?!

After Jamie Lynn Spears released her tell-all memoir earlier today, it seems that Britney Spears “must confess” a few things of her own.

A lot of it seems to be in regard to Britney’s public split with “Cry Me A River” artist Justin Timberlake. The pair had dated from 1999 to 2002. To promote her memoir, “Things I Should Have Said,” Jamie Lynn Spears did an interview with Call Her Daddy podcast on January 18 to talk about the breakup.

Although the couple called it quits after three years of dating, Jamie Lynn revealed that she and her family approved of the couple’s relationship when they first started dating.

“That was probably one of the best times in my whole family’s life,” Jamie Lynn said. “Things were good and we were experiencing the good side of things. But I just remember that he was pretty thoughtful…. I just felt like he was funny.”

She said that she was “so sad” after their public breakup.

“I don’t really know why I was so sad, but I was because I think everybody thought it was forever,” she continued. “But I was so sad first off because my sister was so sad. That also too was the first time I saw [that] maybe I didn’t know everything about the relationship, because perhaps they were protecting me.”

“Obviously, why would they talk to me about anything? It was really sad, though, seeing my sister be so heartbroken,” she added.

Jamie Lynn also talked about how Justin’s hit “Cry Me A River” was allegedly about his breakup with Britney. Britney seemed to respond to the song with her 2003 comeback “Everytime.”

“Looking back with that perspective and seeing how heartbreaking it must’ve been for my sister when ‘Cry Me a River’ came out,” Jamie Lynn continued. “Don’t get me wrong, that’s a way to launch your solo career, but I felt really sad.

“My sister, she wrote that song ‘Everytime,’ and she’s obviously beyond brilliant when it comes to anything creative, and she picked that song out on the piano, and she wrote it, and it still makes me cry because I think about how heartbroken she was.”

“That was his song, but ‘Everytime’ was her song,” she said. “It still breaks my heart to think about that.”

Although Jamie Lynn remembers her sister creating the song “Everytime,” Britney took to Instagram on Tuesday night to share her own memory post-breakup.

“I flew home to Jamie Lynn on the couch watching her tv shows right after Justin and I broke up…” she began. “I was a ghost there !!!!!”

“I had worked my whole life and I didn’t know how to be served by Mamma …” she continued. “Sit there and get served the chocolate milkshakes with the perfectly crushed ice with the secret chunky sugar meanwhile Jamie Lynn is 12, she indulges with the TV for hours then goes to lay out on a raft at the pool.”

“I’m in shock because this was never my life !!!!” Britney added. “Justin’s family was all I knew for many years ...”

“Things were different now and Jamie Lynn had a new Nickelodeon show … All I remember saying was ‘D--- !!! How the hell does a 12 year old land a Nickelodeon show ????’”

“….. HMMMMMMMM …. Well I never got my iced chocolate drink !!!” she continued. “I mean yeah … I’m grown up right ??? But then maybe I might need a little support.”

Britney seems to shift gears a little bit, writing, “It was a People Magazine cover … The people show up and as Jamie Lynn says, I was scared !!!! F--- yeah !!!”

“My Mamma was on pain medication and could barely hold a conversation in the house because her and my dad split and she was more messed up than anything !!!!” she went on. “I remember her sitting on the floor in a conversation and she never got up…”

“And I’m sorry Jamie Lynn, I wasn’t strong enough to do what should have been done … slapped you and Mamma right across your f---ing faces !!!!!”

WOAH! Fans aren’t sure what to think of Britney’s latest message, but she deleted it only twenty minutes after she posted it. Jamie Lynn has yet to respond to Britney’s latest comment.
