Britney Spears, 38, has finally had enough. The singer responded to cruel internet trolls in a long Instagram message on March 17. The bullies had been criticizing Britney for posting similar pictures of herself in a white swimsuit, which she’s claimed is her grandmother’s swimsuit, against a red background. From March 2 to March 5, Britney posted a series of similar photos of herself, with some featuring her longtime boyfriend Sam Asghari.
