Yet another batch of nude photos purportedly of pop singer Demi Lovato have leaked online.

The cell quality photos were first obtained and posted by Egotastic on April 5 and show someone who looks very much like Lovato, 21, in bed with someone who looks very much like her boyfriend, 34-year-old actor, Wilmer Valderrama. Another photo also shows a woman who is alleged to be Lovato wearing leggings, and is completely topless. And while her head is not visible in the frame, at first glance, what appear to be her rather identifiable tattoos are completely visible.

Since the photos leaked, neither Lovato nor Valderrama has officially responded, however, the 'Heart Attack' singer subsequently tweeted a photo of herself wearing boxing gloves, writing in Spanish, 'Soy fuerte. Soy luchadora. Asi que no me subestimen,' which translates to, 'I am strong. I am a fighter. Do not underestimate me.'

This is not the first time alleged nude photos of Lovato have leaked online. Back in August, RadarOnline reported that multiple 'X-rated and self-shot pics' of the singer were being shopped around to numerous outlets, and showed a young woman in various compromising positions, including some in which she is nude in a bathtub and others where she is lying topless in bed..
