Demi Lovato is again facing the alleged naked pictures scandal. On April 4, racy photos of Lovato and her boyfriend went viral on the web. Lovato was seen lying under the sheets with her boyfriend Wilmer. The photos showed the couple making out with each other and even cuddling while wrapped in white sheets.

The photos, which really shocked her fans, were the ones where she has her booty up in the air and her full side with one boob visible.

This is not the first time that Lovato has become a victim to naked selfie pics. In August 2013, the photos of the "Made In The USA" in compromising positions had gone viral web. The images showed Lovato's look alike lying topless on the bed, taking a dip in bathtub and kissing another woman. That time the person who was selling the singer's racy pics had claimed that Lovato is bisexual.

"We have nude/sexual photos of Demi Lovato and was wondering if you would like to buy them ... The girl in the middle row, last pic is our friend and is a girl Demi had a fling with for some time on and off," the source had reportedly told Celebslam as reported by Hollywoodlife.

Though the 2013 pictures were never confirmed to be of Demi's, this time she is not keeping quiet regarding her racy pics scandal. She took to Twitter to express her anger and disappointment and wrote: "Soy fuerte. Soy luchadora. Asi que no me subestimen."

The message in english means: "I am strong. I am a fighter. Do not underestimate me."

In the past few months, it is not only Demi who has become a victim to nude pics controversy. There have been many stars including Jennete McCurdy, Ariana Grande and Emma Stone. Let us know your thoughts in the nude photo scandal of various stars. Do you think they are some kind of public gimmick?
