Britney Spears is back in her bikini, and fans no doubt noticed that she's looking much slimmer. Shortly before the weekend, the 43-year-old updated her Instagram from a yacht, looking in good spirits as she filmed a selfie video. Smiling into the camera and sticking her tongue out, Britney showed off her curves in a two-piece she's already worn on her feed, but this time, the "Toxic" star was looking more slender. Spears, who suffers from bipolar disorder, has been worrying fans with her recent posts, and her followers might just have more to worry about. In the last month, the pop star has freaked fans out with her messy home, with 2025 also seeing her saying she'd "adopted" a "baby girl."
