Britney Spears’ mother Lynne has allegedly been profiting off her daughter during their estrangement – by selling off the popstar’s clothing and accessories online and in a local consignment shop for the last five years, insiders have revealed.

It is the latest blow for the troubled popstar, 41, who claimed her family saw her as nothing more than a ‘cashflow’ in her bombshell new memoir, The Woman in Me – and who sources say would be ‘fuming’ to learn that her personal belongings are being sold.

Lynne, 68, is said to have started selling her daughter’s clothing in 2018 at Connie’s Jewelry and Gifts in Kentwood, Louisiana – which is owned by Britney’s childhood friend Cortney Brabham’s family.

A Spears family insider has claimed Lynne has ‘easily made thousands of dollars in profit’ – adding that Britney has ‘no clue’ about any of this.

It comes as Lynne denied selling Britney’s childhood dolls and journals, insisting she wouldn’t be so ‘cruel’.

‘When Britney would come home early in her career, she would unload her clothes at her mom’s house in Kentwood. This also included things she wore on tours and her personal clothes,’ an insider told DailyMail.com exclusively.

‘She has no clue and would be fuming if she did.’

Items on sale at the store include the Judi Rosen jacket worn by Britney on TRL in 2002, as well as fur jackets, leather pants, sweaters and shoes. Not all of the items were worn publicly by the singer.

The insider claims Lynne also sold – and is still selling – her superstar daughter’s designer duds on a popular fashion commerce site through an account owned by Tatum Solis – who even models the items and posts them alongside photos of Britney.

The countless fashion hand-me-downs include the Miss Capezio Vintage Butterfly Cowboy Boots she wore at the 2003 Kids Choice Awards, and a pair of Marc Jacobs designer black sunglasses which she was frequently pictured wearing in public.

Tatum herself appears to have dipped into the Toxic singer’s stash, purchasing the white satin jacket Britney wore to open her 2011 Femme Fatale Tour.

‘Tatum wears the jacket often to functions,’ the source revealed. ‘And she always brags about how it was worn by Britney. It even has Britney’s signature on the inside.’

In her memoir, Britney claimed that after getting released from a mental facility in 2019 – where she was forced to take Lithium – she returned home to Kentwood to find her clothes had been ‘thrown away’ by her family.

‘When I saw the empty shelves, I felt an overwhelming sadness,’ she wrote. ‘And my family had thrown them in the trash just like they’d thrown me away. I’ve been through a lot. The reason why I’m alive today is because I know joy. It was time to find God again.’

The source added: ‘Britney had hundreds of pairs of jeans at one time. She would come back home to Kentwood and just unload all of this stuff with her mom. Lynne held onto everything.’

They alleged that she has also been conducting private sales of her daughter’s possessions.

‘Lynne needed the money to buy Christmas presents for her grandchildren,’ the source added.

However Tatum insisted that it was a misunderstanding and that the items were all replicas or extras of Britney’s own belongings.

‘I have never sold, nor would I ever sell anything belonging to Britney,’ she said. ‘The white jacket was given to Lynne, and Britney had a separate one.

‘I had the same 2003 boots that Britney owned and I used her photo on Poshmark because I was like “look they were made famous by Britney these are replicas”.’

Lynne appeared to address her daughter’s claims that she disposed of her belongings, insisting she wouldn’t be so ‘cruel’.

Writing on Instagram on Thursday, she offered to send the ‘special’ items in question to Britney, as she professed her love for her estranged daughter.

Alongside pictures of the dolls and a journal, she wrote: ‘I’m not sure who told you I got rid of your dolls and journals but I would never do that! That would be cruel because I know how much they mean to you. They are special to me too because of the years we spent collecting them.

‘Of course I still have your things, and I am happy to send them to you if you’d like me to. Please let me know and know how much I love you!’

Lynne – who still lives in the $2 million mansion that Britney built for her in 2001 –  recently went back to work as a substitute teacher in Kentwood.

‘She is struggling to pay her bills, but she has already substituted for several classes at [a local school],’ the insider previously told DailyMail.com.

Substitute teachers working in the area can expect to earn around $15 an hour.

According to court documents, Lynne filed a petition in November 2021 to request that Britney’s estate pay the $660,000 attorney bill for her conservatorship lawyers.

But in April 2022, Britney’s own lawyer Mathew Rosengart argued against that petition in court, stating that ‘there is no legal authority supporting’ Lynne’s claims that she should be able to collect funds from her daughter’s estate.

Court documents reveal that Rosengart further alleged that Britney had spent approximately $1.7 million on her mother over the years, claiming that Lynne had ‘for at least a decade resided in a large, expansive house owned by Britney’, who – he said – also ‘paid Lynne Spears’ utilities, telephone services, insurance, property taxes, landscaping, pool work, pest control, repairs and maintenance’.

Legal paperwork obtained by The Blast in October of that same year revealed that Lynne had withdrawn her $660,000 claim.

Lynne filed for chapter 7 – liquidation bankruptcy – in 1998. She had owned five companies in the past 20 years, including Britney Online, inc. and One More Time Music, Inc. but is no longer involved in any of them.

She no longer owns her own property, having sold Britney’s childhood home for $275,000 in 2021.

In Lynne’s 2008 autobiography Through the Storm she said she blamed herself for Britney’s demise.

‘When her life was such a success, what did she need me for? And when things took a turn for the worse, I was out, because other people – dancers, managers – were closer to her, and with her day and night,’ Lynne wrote.

‘Being a mother, you can’t help but have regrets about what you did and didn’t do for your kids, and I’m no different,’ admitted Lynne.
