Britney Spears has once again hit out at sister Jamie Lynn Spears in a scathing Instagram post.
The sisters have been embroiled in a war of words since Britney's conservatorship ended and things intensified when younger sis Jamie Lynn, 30, released her latest memoir.
But, as the Baby One More Time singer, 40, has proven lately, she's not prepared to lie down any longer and has gone in hard on her sibling for telling lies and trying to "run the house".
