Photos of the 21-year-old in bed with 34-year-old star-fucker boyfriend Wilmer Valderrama leaked online over the weekend, in addition to some nude solo selfies from Demi -- including one explicit full-frontal shot.
The "Heart Attack" songstress responded to the scandal last night on Twitter in a typically self-affirming Demi Lovato kinda way.
"Soy fuerte. Soy luchadora. Asi que no me subestimen," she tweeted in Spanish, which translates to: “I am strong. I am a fighter. Do not underestimate me.”
Hmm, sounds like someone has been listening to some Christina Aguilera!
