If you broke Charlie Puth’s heart, square up! On Wednesday, Charlie, with a buzz cut and that same beautifully scarred eyebrow, released his new single “I Warned Myself.” It is a song about love and loss, secrets and lies — basically a breakup. But Charlie knew better, warned himself, and hooked up with this woman anyway! “I warned myself that I shouldn’t play with fire,” he sings. “But I can tell that I’ll do it one more time / Don’t trust in myself, no good for my health / You messed with my heart, now you’re the reason why.” Okay, but who exactly is the reason why? Was it his ex-girlfriend Halston Sage? Was it his old “We Don’t Talk Anymore” flame Selena Gomez? Was it this season’s Chuck-Wendy conflict on Billions, a show Charlie has proved himself a fan of? CP Family, we await the results of your federal investigation.
