Britney Spears takes ‘brutal swipe’ at I’m A Celeb star sister Jamie Lynn with cryptic post ahead of jungle stint

BRITNEY Spears appeared to take a "brutal swipe" at her sister Jamie Lynn after she announced she had signed up to I'm A Celebrity UK.

The Toxic hitmaker, 41, has had a fractured relationship with her sister since 2018 after Jamie Lynn became a partial trustee of Britney's estate, according to a report by ,

And now, things could get tricky once again thanks to Jamie Lynn signing up for I'm A Celebrity.

Taking to Instagram, Britney shared a cryptic message just minutes after the news broke of Jamie Lynn's appearance on the ITV jungle show.

She posted a quote originally said by Ernest Hemingway, which read: "All things truly wicked start from innocence," and captioned it with a pink flower emoji.

The pop star did not elaborate any further, but her loyal fans began speculating that the quote was directed at her sister.

One follower wrote: "‘Your sister for example!! She’s about to go in the Jungle and us Brits are RUTHLESS.. we’ve got your back hun."

Another posted: "Hi Brittany I hope you enjoy Jamie Lynn suffering on I’m A Celeb I’ll definitely be putting my votes on her to do EVERY bush tucker trail."

Actress Jamie Lynn, 32, was born a decade after her singing superstar sister, and spent much of her childhood touring with Britney, 41, and the rest of their family.

Despite sharing a strong bond in their youth, things became strained when Jamie Lynn became a partial trustee of Britney's estate.

It meant the younger sister would have a degree of control over the singer's assets, which were stored in her SJB Revocable Trust and intended to be used to help her children should she die.

Britney didn't comment at the time. Jamie Lynn then publicly commented on her sister's situation, appearing to criticise the #FreeBritney movement as the backlash over the conservatorship gained momentum.

Shortly after Britney was checked into a mental health facility, which fans claimed was against her will, Jamie Lynn shared a photo of her protecting her older sister from the paparazzi.

She captioned it: “10 years ago, who was there?? I have been here long before anyone else and I’ll be here long after. I love my sister with everything I have. So anyone or anything that speaks to the contrary can GTFOH with all the comments about what you don’t understand.”

Later that year, the girls appeared to be on good terms, with Britney dying her hair brown and telling fans on social media that she had been inspired by her sister's change-up earlier in 2019.
