Britney Spears Calls On Sister To Take Lie Detector Test In Furious Rant Following TV Interview

Britney Spears has taken to Instagram in a scathing rant to further call out her sister's best-selling memoir following a TV appearance.

Spears - who was recently freed from a conservatorship which lasted for over 13 years - has vowed to seek justice against family members who she feels let her down, whether that be speaking out about how her parents should be in jail, or describing her sister, Jamie Lynn, as a 'mean a**'.

However, in response to Lynn having recently released a memoir which the star slammed as being written 'at her expense,' the Toxic singer has since taken to social media to post footage of discussions surrounding the best selling author, and to accuse Lynn of 'lying through [her] teeth'.

In the first clip posted by Spears from US talk show The Real, a group of hosts can be seen discussing the 'rivalry' between the sisters.

One says: 'The things I should have said to my sister and my sister alone, but instead I decided to make a book for profit.

'Loyalty in my family is so important, loyalty in my sisterhood is so important. If you wanted to clear your name, who is it important to clear your name to? Your sister or the masses of people?,' she stated.

The second clip shows the host of Ninja Warrior and the Talk of CBS Akbar Gbajabiamila drawing comparisons between Lynn's memoir and that of Will Smith.

'I will say Will Smith came up with his book last year and what was interesting was how he brought everyone in that was mentioned in the book and got their approval,' he noted.

Gbajabiamila explained the importance of the difference in 'perspective'. 'You can be in the same family dynamic like with the Spears, but see the situation completely different from your own childhood wounds, from your own filter, where you at that place right there, at that place right then, and I think that could be unfair.

'I don't know this to be true, but if you didn't talk to your sister about putting all of this information or your perspective on how you see it, that's not fair. I think that's something you resolve behind closed doors, try to resolve that first,' he concluded.

Spears took to Instagram to agree with the comments made by the hosts, branding her sister as 'scum'.

She said: '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 !!!!'

The star accused her 'whole family' - including Lynn - of pretending to not know, which she called, 'B*llsh*t'.

'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!!!,' she stated.

The singer then went on to sarcastically congratulate her sister, expressing how she wasn't 'surprised at all' that the book has become a 'best seller'.

'The nerve of you to sell a book now and talk sh*t but your f*cking lying just like you lied about Alexa Nikolas !!!!,' she stated.

Spears concluded, '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.'
