Britney Spears has appeared to shade her sister Jamie Lynn in a new video posted on Instagram.

The princess of pop has posted a video of her dancing to a song by Selena Gomez. The song's title seemed to be taking aim at Spears' younger sister, who has recently published a memoir.

Britney Spears Seems To Take Aim At Her Sister Jamie Lynn On Instagram

In a new Instagram video, Spears shows off her moves, dancing to 'Bad Liar' by Selena Gomez.

But Britney's performance isn't the only thing that caught her nearly 40 million followers' eye.

"Me and the song Bad Liar … How appropriate is that ???" Spears wrote in the caption.

Some of the singer's fans immediately connected the dot and were convinced that Spears were referring to her sister, subtly calling her a liar.

"PARA TU HERMANA," a Spanish-speaking fan wrote, hinting at Britney posting the video "for her sister".

"Their lies are getting exposed, don't worry. We believe YOU and you only," another follower said.

"this drag is EVERYTHING," was another comment.

Britney And Her Sister's Fallout Over Jamie Lynn's Tell-All Book

Earlier this year, Jamie Lynn announced she would publish a tell-all book titled 'Things I Should Have Said'.

While the 'Sweet Magnolias' actress assured she isn't looking for fame and money and will even donate part of the profits to charity, Britney and many of her fans thinks her younger sister is profiting off her story, and that Jamie Lynn knew about the psychological abuse Britney was subjected to during her conservatorship.

Last year, Spears' 13-year-long conservatorship was terminated after a long legal battle. Los Angeles judge Brenda Penny announced her decision, after having previously ruled to remove Britney's father Jamie Spear as conservator.

Ever since Jamie Lynn went public with her memoir, published in January this year, and her intention to go on a book tour, Britney has slammed her sister on her Instagram. Despite Jamie Lynn took a step back and decided not to go on tour, she is still on the receiving end of some shade from her big sister and her fans.

Britney has previously said that Jamie Lynn wasn't even around for parts of her life and therefore couldn't possibly comment on that tough time. Jamie Lynn has repeated that the book isn't about Britney, but it was somewhat contradicted by extracts of the book that appear to focus on Britney.

The book reignited the feud between Spears and her younger sister, with Britney unfollowing Jamie Lynn on social media.
