LOS ANGELES, April 7 (UPI) -- Demi Lovato is ready to fight a recent leak of photos that show her nude and in bed with on and off beau Wilmer Valderrama.
The 21-year-old singer took to Twitter Saturday to share a message that reads: "Soy fuerte. Soy luchadora. Asi que no me subestimen," which is Spanish for: "I'm strong. I am a fighter. So do not underestimate me."
