Demi Lovato's alleged naked pictures surface online

Demi Lovato has reportedly been caught up in a naked picture scandal.

Some photos of a woman who resembles the 21-year-old 'Neon Lights' hitmaker surfaced on the internet on April 5.

The snaps shows the woman taking selfies in bed and cuddling with a man, who looks similar to Lovato's on-off boyfriend Wilmer Valderrama, reported Ace Showbiz.

The former judge of 'The X Factor' made no comments about the photographs. However, after the news, she took to Twitter to write, "I am strong. I am a fighter. So do not underestimate me".

This is the second time Lovato has been hit with naked photo scandal.
