Don’t mess with Demi Lovato. That’s the lesson we’re taking away from this past week. After nude photos — supposedly of the 21-year-old — began making the rounds online, she had some choice words. “I am strong. I am a fighter. Do not underestimate me,” she cryptically tweeted (in Spanish) on April 5.

Now she’s taken to Twitter once again to air her grievances about a recent article discussing on-again, off-again boyfriend Wilmer Valderrama. The 34-year-old appears (or at least someone who looks just like him, anyway) in those sexy snaps; now he got a full character examination at the hands of Daily Beast blogger Amy Zimmerman who writes, “Wilmer Valderrama’s so culturally irrelevant, the commodification of his young girlfriend's body has nudged him and his playboy ways back into the current celebrity conversation.”

The article, titled “Why Women Want Hollywood Lothario Wilmer Valderrama,” describes the actor as having “obvious eccentricities and general aura of grossness.” It also suggests the reason he’s had so much luck “convinc[ing] a bunch of beautiful women to fall in love with him” is because of his status as a “Venezuelan man-trophy.”

Not surprisingly, Dems’ isn’t taking that kind of talk sitting down. She headed online on April 9 to tell Amy and her publication what she thinks of their latest piece. “@thedailybeast such a classy ‘news site’ you are. Writing horrible things about people you know NOTHING about. Get a LIFE you ignorant fks,” she tweeted.

Ouch!
