Britney Spears is calling out her enemies as she begins a new chapter in life.

Nearly two years after her memoir The Woman in Me became a bestseller, the singer revealed she's writing two fiction novels and raved over how beneficial the process has been for her mental health - but she then went into an angry anecdote about those who have held her back in life.

"I've felt like half the world was shady to me for some reason energetically, and I think it's because I stopped dreaming the way I used to, and I had no spiritual connection," the pop star explained.

Spears then targeted those who have done her wrong in the past, spilling, "But let me tell you guys a secret... to those who are listening, because believe it or not, those closest to you sometimes will be the main ones to do whatever they can to stop you from having the life you deserve, even lie to you. If I told you guys you wouldn't believe me and it's not something I ever want to share πŸŒΉπŸ˜œπŸ˜œπŸ€·β™€οΈπŸ€·β™€οΈ."

The lengthy caption was accompanied by a video set to Tove Lo's Habits (Stay High) and showed Spears modeling different outfits, including a fedora with a button-down shirt and miniskirt, a blue skirt she pulled down to her hips and an off-the shoulder frock.

Spears risked having a wardrobe mishap, as at one point, she was taking off her dress from the top down on camera.
