Britney Spears has slammed her sister Jamie Lynn as "f***ing hateful" and a "selfish little brat" in a new post.

The 40-year-old popstar - who regained control of her assets after the conservatorship governed by her family was terminated in November 2021 - took to Instagram to slam Jamie Lynn for saying her decision to buy their mother a house after she had made it big in the music industry was "a f***ing weird thing to do."

Britney wrote: "You selfish little brat!!! Saying how weird and dumb it was that I had bought a house for Mamma !!! She was so proud and you told that interview girl that it was just weird … LIKE I GUESS I WILL JUST WALK IN THESE HALLS … Why did you say that ???"

Britney then went on to accuse Jamie Lynn of being "f****** hateful towards their mother - who divorced from their father Jamie in 2002 - as she continued her tirade.

She said: "My mouth was on the floor the way you talked back to Mamma when I came home … Shocked out of my lined !!!!!! You were f****ng hateful to her and I know Mamma had been lazy with me but I'm sorry you deserved WAY MORE than a purse knocked at you by Mamma …
