Britney Spears has hit back at her sister Jamie Lynn Spears after she claimed life as her sibling was "hard."
The chart-topping star took to Instagram to share a scathing response to the claims from her sister, 31, as well as other members of her family.
Britney, 41, uploaded a series of often incoherent rants after Jamie Lynn appeared on reality TV show Special Forces: World's Toughest Test on Wednesday and referenced her superstar sister in a video where she broke down in tears as she discussed her childhood.
Jamie Lynn had followed in her sister's footsteps as a child star but stepped away from fame in 2007 when she fell pregnant at 16.
Talking on the show she said: "Growing up, my sister became famous, worldwide famous, when I was very young. I’m so proud of her, love her to death, but I don’t know. Sometimes I feel like I don’t really have anything for myself. I struggle with self-esteem all the time."
The comments have not gone down well with her older sibling who took to Instagram to lash out at Jamie Lynn.
She posted: "Are we gonna say it was hard being my sister ???? Hmmmmmmmmmmm.... really ??? Well this was my spa plan at Vegas as my childhood friends had their heads held high with a seat for toes and nails and a bottle of champagne for each one of them while I STOOD AT THE DOOR not allowed to go in...
"But bet ur bottom dollar they be gotten their entertainment from me that night !!!!! I've learned from the BEST... do we dare set aside our SELF CARE AND ACKNOWLEDGE a childhood friend ???? WHY no !!!!"
Her rant raged on as she appeared to make threats about "spitting in the faces" of her family.
Britney continued: " WHY no !!!! We teach her the MEANING OF MEAN and then throw her away in the end with no self rights !!!! You want me to share it on Telly ??? I'd rather spit in their faces and trash them on Instagram cause that's all my family has ever been to me !!!!"
Britney then seemingly discussed an old injury as she described " Pssss here are pics of what nerve damage can do... which I have right side of my body and goes numb every night !!! Not a victim story or crying about it because I was never a big deal..."
She then appeared to take aim at her father Jamie describing alleged antics on his part.
She wrote: "I sat in a chair for 10 hours a day and no rights for 4 months !!!' she wrote. 'They hurt me and nothing was done except that I lost 15 years of my life with my family owning my name ...
"Subjected to being an angel while my dad has 5 women on his tour bus drinking that cup of coffee ... so cool and smooth it must have been nice owning my name for 15 years... it honestly blows my mind the hardships you say you have had with having me as your sister...
"I'm sorry you feel that way but don't ever poke at my broken foot in a kitchen telling me to go to the doctor because my foot infection might infect your royal children !!!'
Britney then posted a second rant alongside a photo of the sun blazing in the sky.
She said: "'For a woman whose name was stolen by her family after 15 years and was told what to do and was extremely punished if I spoke up as a woman to be BORN… How do I begin to find my NEW hands and legs every day ???
"I realize over and over again I'm not owned by my family !!! I try to find meaning in every movement I make daily !!! I hold the test of time when I finally breathe in and am not shaken scared … demoralized… or humiliated as I find my body !!!
"I find my name and it's not a threat … IT’S MY SIN IN WEAKNESS TO BE VULNERABLE AND HUMAN !!! I listen to the child within … only the child knows !!! I have nerve damage on the side of my body … my hand goes numb when I sleep !!! It shoots to my head and it hurts deeply !!! I sleep a lot because of the pain. God is the one and only cure PERIOD !!!"
Britney then appeared to compare her life to Hollywood star Reese Witherspoon as well as Beyonce as the tirade continued.
She wrote: "This is not a victim story yet but it’s definitely a heart-wrenching and humbling way to share tears and complain for hours and hours FOR CAMERAS supporting you which I never had.
"I know I seem to make my Instagram picture perfect like the lovely Reese Witherspoon but it honestly helps my mental health … there are things people don't know and I've never shared because it's sad as f••k and embarrassing !!!
"It makes it worse when I share because people ask more questions like my mom !!! AS IF SHE DOESN’T KNOW !!! What the f••k do you think Beyoncé’s mom would do if they did that to her daughter ???"
The star finished up by commenting: "She would look at them like they have lost there f••king minds … THAT’S IT !!! My name hasn't been here in 15 years … I want people to know what's up and hey we are gonna go LOW ?? I’M REAL GOOD AT GETTING DOWN !!!"
