Britney Spears didn’t hold back when it came to her recounting a difficult time with her younger sister Jamie Lynn Spears in a section of her upcoming memoir The Woman In Me.

In one shocking excerpt, the 41-year-old pop superstar called Jamie Lynn a ‘total b**ch’ — even though she was describing her sister when she was just 11 years old.

Britney recalled being fed up with her sister’s allegedly terrible behavior when she returned home from her tour in 2002, a source shared with Us Weekly on Thursday.

The catty excerpt leaked just days after an excerpt leaked in which Britney claimed that she had an abortion after getting pregnant at just 19 because her then-boyfriend Justin Timberlake ‘wasn’t ready to be a father.’

In the newest nugget from her memoir, the songstress lambasted Jamie Lynn’s behavior at their family home due to her poor treatment of their mother, who was struggling in the wake of her split.

Extracts from Britney Spears’ upcoming leaked memoir

Britney wrote that she arrived home from tour to discover that Jamie Lynn — now 32 — ‘ruled’ their home.

She reportedly added that she felt ‘betrayed’ by how the rising actress — who would star on Nickelodeon’s Zoey 101 three years later — had ‘changed’ while she was away from home.

The Toxic singer also delved into Jamie Lynn’s decision to write her own memoir, Things I Should Have Said, which was published in January 2022.

According to the source, she saved some vitriol for the Zoey 102 star for the publication of her book, though it’s unclear if it was due to Jamie Lynn’s claims about her older sister, or because she tried to beat her to market with a tell-all book of her own.

Britney has gone back and forth between seemingly despising her sister and sharing her love for her publicly in recent months.

Although she initially blasted every member of her family in the final days of her conservatorship and the immediate aftermath of its dissolution, she has occasionally reached out with public olive branches on social media.

Earlier this summer, Britney shocked her fans when she claimed to have visited Jamie Lynn on the set of her series revival movie Zoey 102, even though the movie appeared to have done much of its filming on the East Coast.

Last month, TMZ reported that the songwriter was ‘fully supportive’ of her sister joining Dancing With The Stars, even though several of Britney’s fans blasted Jamie Lynn for joining the competitive show, as they thought she was merely riding on her older sister’s coattails.

Britney was given advance notice about her sister joining the show, and she not only ‘took it well’ but was reportedly ‘excited’ about the development.

However, Jamie Lynn only made it two week two before she was voted off the show. It’s unclear if Britney’s fans, some of whom had pledged to try to vote her off, played a decisive role in the move, but she had received fairly strong scores from the judging panel.

It’s unclear if Britney’s thaw with Jamie Lynn will las, and her other attempt to reconcile with her mother Lynne appears to have failed.

Although her mother was seen visiting Britney earlier this year, shortly before her split from husband Sam Asghari, the two are reportedly estranged once again.
