Demi Lovato downplayed the apparent leak of one of her private photos, brushing off the incident with a pair of tweets featuring laughing emoji. "I love how everyone's freaking out about one picture," Lovato wrote. "It's not nude and it's just cleavage." She followed that by noting she's voluntarily shared nude photos of herself before: Lovato posed for a series of au natural images in a 2015 Vanity Fair photoshoot. "Besides the world has seen me nude BY CHOICE before.." she wrote in the second tweet, adding three of the laughing emoticon smiley faces. "#vanityfair #nicetry #cleavagegameonpoint #myboobsarenteventhatbig #angles." Lovato is one of several big-name female stars, including Emma Watson, who have reportedly fallen victim to private-photo hacks in recent weeks.
