Demi Lovato posted some fighting words on Twitter after alleged nude photos of the 21-year-old pop star surfaced online April 5.

Demi Lovato Naked Photo Scandal

Lovato, who is currently on her “Neon Lights Tour,” has not officially commented on the photos, which feature a topless woman who appears to be Lovato, lying in bed with a man resembling Lovato’s longtime on-again-off-again boyfriend Wilmer Valderrama.

The scandalous photos reportedly do not include the woman’s face, but a few of Lovato’s signature tattoos are clearly visible. There is also a photo of a woman completely naked covering half her face, but reports are skeptical of the authenticity of the photos.

This is not the first time Lovato has been the victim of allegedly leaked photos. In August, nude photos of the singer were being shopped around, but were never sold.

Demi Lovato Fights Back

Neither Lovato nor Valderrama have released any kind of statement addressing the rumors of the naked photos, but Lovato did take to Twitter on April 5 to post a message to her haters. The singer posted a photo of herself in fighting position, wearing boxing gloves, with the caption, “Soy fuerte. Soy luchadora. Asi que no me subestimen.”

The caption translates to “I am strong. I am a fighter. Do not underestimate me.”
