It seems like every other week, we turn on our computers only to find a new story about private pictures from celebrities somehow making their way from their phones to the Internet. This week? It's Demi Lovato.

Intimate pictures of Demi and boyfriend Wilmer Valderrama circulated on the Internet on Friday and Saturday which show Demi and Wilmer sharing intimate moments in bed. A few other pics appear to be selfies in of Demi wrapped in sheets. While those pictures aren't too risque, there are others floating around that are more revealing of the former 'X Factor' judge, yet also more questionable in terms of authenticity.

The other alleged photos include one shot of Demi looking into the camera wearing nothing and lying on her front in bed. Another picture supposedly shows the singer completely topless from the shoulders down in what appears to be a mirror selfie. In that picture, however, Demi's face isn't shown.

Nobody has confirmed the authenticity of these pictures although the ones with Wilmer and Demi in them look pretty harmless. It seems Demi herself isn't going to let this scandal phase her, as she took to Twitter to say:

Translation: "I am strong. I am a fighter. So do not underestimate me."

This isn't the first time Demi has had to battle for her privacy online. In June of 2012, Demi had to fight another set of leaked pics online in which she is seen posing a series of seductive poses but with no actual nudity.
