Billie Eilish has a few words for Benny Blanco after seeing his TikTok about Charlie Puth.

Blanco (a.k.a. Benjamin LevinPuth has been making videos mocking his voice, and telling him “Shut up Charlie!” The 30-year-old producer, singer and songwriter decided that he had “finally to say something.”

Puth commented in November that “these videos were actually funny at first,” I don’t know the reason you have been so cruel to me over these last few months. But it hurts my feelings. “I used to admire you. I don’t know why this has happened.”

Still, Blanco didn’t stop. Blanco, 33 years old, replied that he knew why he made the video. “It’s because of you, Puth,” he said. “Look at you: You sit in a room all day and make TikToks…Dude, what the hell’s wrong with you? Take a look at your hair. You look like you have a toupee, a wig or some other accessory on your hair. Take control and have a fabulous haircut.
