Posting on Instagram, the 40-year-old dipped and danced in a gym wearing a skin tight, red bodysuit and black stilleto heels.

When she twirled, she showed off her bare butt in the tight outfit’s thong.

The singer explained: “This is 13 seconds of me in heels, before I dyed my hair purple.

“This is a tease of what’s to come !!!! My song ‘Get Naked’ !!!

“Hope you guys are having a great day !!!!!”

She added a little behind the scenes factoid, sharing, “Pss, No hair and make up !!! Just PLAYING around folks !!!!”

BRITNEY’S BATTLE

Britney has been in a playful mood since she gained control of her estate, following her legal victory after being freed from her 13-year-conservatorship.

But she’s been deadly serious about her feelings toward her sister Jamie Lynn, calling her “scum” and accused her of “lying,” as her sibling’s tell-all book was declared a national best seller.

The Baby One More Time popstar, took to her Instagram account to rip her younger sister, who recently released her memoir, Things I Should Have Said.

The pair have become embroiled in a nasty feud, with Brit threatening to sue Jamie Lynn for derogatory claims before branding her a “brat” for her new memoir.

JAMIE LYNN’S BESTSELLER

In the latest war of words, mom of two Britney uploaded two clips from TV shows The Talk and The Real, both of which featured panels taking the singer’s side.

They argued Jamie Lynn‘s words would have been best said in private rather than plastered over the new release.

Yet it was in the caption that Brit showed her true strength of feeling as she raged: “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!!!!

“My whole family including you is saying YOU DIDN’T KNOW …. Bulls**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!!! Congrats best seller … I’m not surprised at all!!!

“The nerve of you to sell a book now and talk s**t but your f**king lying just like you lied about Alexa Nikolas!!!!

“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!!!!”

The pop princess ended her scathing message with the words: “You are scum, Jamie Lynn.”

BRITNEY BLASTS BACK

This marks the latest in a series of events since Britney gained back control of her life last year after her conservatorship officially ended.

Ever since then. Britney has been extremely vocal, slamming her family members especially younger sister.

In fact, the performer recently shared she wish she would have “slapped” her sibling, as well as her mother Lynne.

The US Sun has since exclusively reported how Britney will fight back in the form of releasing her own tell-all book to “set the record straight.”
