Britney Spears Calls Sister Jamie Lynn Spears ‘Scum’!

Pop star Britney Spears can’ catch a break from her dad Jamie Spears and his lawyers wanting a depo date or her sister Jamie Lynn Spears book these days…

CelebnMusic247.com reports that Britney Spears is now calling her sister Jamie Lynn ‘scum’ yet again — in a scathing new Instagram post shared on Friday.

Jamie Lynn Spears book is a National best seller…gee we wonder why?

Britney Spears took to Insta calling out Jamie writing:

National best seller ???? DUH ? …. the timing of your book was unbelievable Jamie Lynn … especially knowing the whole world had no clue what was really done to me !!!! My whole family including you is saying YOU DIDN’T KNOW …. Bullshit !!! But what these women are saying here is pretty clear !!!! I’m just kinda shocked that more people like these real soul sisters aren’t telling it like it is !!! Congrats best seller … I’m not surprised at all ????? !!! The nerve of you to sell a book now and talk shit but your fucking lying just like you lied about Alexa Nikolas !!!! I wish you would take a lie detector test so all these masses of people see you’re lying through your teeth about me !!!! I wish the almighty, Lord would could come down and show this whole world that you’re lying and making money off of me !!!! You are scum, Jamie Lynn..

Jamie Lynn, 30, described herself as “a NATIONAL BEST SELLING AUTHOR!” in a Friday Instagram post of her own. (above)

As Britney pointed out, the book was released only two months after she was freed from a controversial conservatorship that had controlled her personal, medical and financial affairs for nearly 14 years. With the help of attorney Mathew S. Rosengart, it was finally dissolved in November.

Britney’s post declaimed:

My whole family including you is saying YOU DIDN’T KNOW…Bulls–t !!!

The singer has previously criticized her family members — also including dad Jamie, mom Lynne and brother Bryan Spears — for their roles in the restrictive legal arrangement that she has called “abusive.”

The post was accompanied by a montage of media personalities — including Adrienne Bailon of “The Real” — lambasting Jamie Lynn for detailing private moments of Britney’s life in the tome and in a succession of media appearances to promote it.
