If you ever thought Britney Spears was too amazing to be human, you were right (well, sort of). The singer took to Instagram on Thursday to share a cute photo of herself swimming in a Pool while wearing a Mermaid outfit. Britney, who has her arms around her two sons, Sean and Jayden, smiles at the camera while rocking blue "flippers." She captioned the sunny shot, "The Mermaid life."
