Demi Lovato isn’t the type to mince words or shy away from a fight. Perez Hilton found that out first-hand on Monday as the pop singer roasted the gossip columnist on Twitter.

Without identifying her target, Lovato boasted that she got to sing “Sorry Not Sorry” to the face of “one of USA’s most notorious bullies. It felt so f---king great.” She followed up by insisting he would remain nameless “because he doesn’t deserve the relevance that he doesn’t have anymore.”

The "Confident" singer's double-whammy comes after Hilton gave a passable review for her March 3 Tell Me You Love Me show at the MGM Grand Garden Arena. “I am a Demi Lovato fan. She wasn’t bad. She was better than before,” he said in his video recap. “I have nothing bad to say.”
