Dove Cameron is avoiding tan lines in the best way. The singer, 29, shared a steamy picture of herself reading a book outside via Instagram on Thursday, September 11. In the pic, she went topless as she soaked up the sun. Cameron covered her chest with a book as she gazed into the camera. Cameron went makeup-free in the sultry snap, showing off just how hydrated and dewy her skin is. She flipped her brunette hair over her shoulder and leaned against a white couch. The actress added a touch of sparkle to her ensemble with gold rings and a silver necklace with a blue jewel pendant.
