Could a Drake and Justin Bieber collab be on the horizon? On Sunday, Bieber stirred up buzz by posting a cryptic Instagram carousel—three vague images and a moody selfie—captioned, “Dm me if u wanna make music together.” Fans quickly jumped into the comments, but it was fellow artists who really lit things up. Drake playfully replied, “I DM’d but no reply.” Despite the attention, Bieber didn’t respond to Drake—or to other musicians who chimed in, including Big Sean, Kehlani, Jaden Smith, and country singer Bailey Zimmerman.
