Britney Spears wants a 2.0 of the "Southern chick" wrestling matches she used to have with sister Jamie Lynn Spears. The 39-year-old pop princess today admitted she was late in wishing her little sibling a happy birthday, although the "Toxic" singer did dedicate an entire Instagram update to the Netflix star. Posting for her 29.2 million followers on Friday, Britney shared a rare throwback of herself and the "Zoey 101" alum, and the caption was fighting talk. Check it out below.

Scroll for the photo, one that included Britney, her sister, plus Britney's once boyfriend, singer Justin Timberlake. The throwback showed Jamie Lynn very young and seated in a cute top and glasses as she was kept company by Britney, with the Grammy winner seemingly having a laugh as the three hung out with another female.

Posts from Britney, these days bringing her reaction to "Framing Britney Spears" documentary, are rarely without an enthusiastic caption. The blonde took to hers with a giant gush, also revealing that Jamie Lynn used to pin her to the ground.

Shouting out the "Sweet Magnolias" actress, Britney opened: "Happy belated birthday to this beautiful soul ??? !!! I love you so much and damn it I wish I was as smart as you at 30 !!!! It's weird to say that I was basically your momma when you were younger and yes I'm still older but your soul is and always has been wise !!!!"

Britney, who recently listed Jamie Lynn as one of her seven most-inspiring women, said she is "truly and genuinely inspired" by her sister's "path."

Calling mom of two Jamie Lynn "So DAMN STRONG," Britney then recalled her youth.

"We play wrestled at home (such classy Southern chicks) ?????‍♀️??‍♀️ and you put me to the floor in literally two seconds after I gave all my might ?????? … I’ll never forget it !!! Maybe we should have a rematch ???? ..," she continued, joking that things "might have changed" in the past six years.

Jamie Lynn made 2020 headlines for turning 29 in quarantine and calling it "crappy times." More photos after the shot.

Britney has been receiving support from more than just the fans amid her 2008-commenced conservatorship battle.

Alongside boyfriend Sam Asghari backing her, Britney has the support of Jamie Lynn, who last year took to her Instagram story with daggers, writing: "Dear media, try not to repeat the mistakes of your past," adding: "Look where that got us. Do better. Everyone you meet is fighting a battle you know nothing about. Be kind. Always."
