Justin Bieber took to Instagram to potentially confirm the rumor that he is working with Ariana Grande.

On Sunday (April 14), Bieber liked a comment from a fan (@jaileyhouse) on Instagram that read, "justin drew bieber I DARE YOU to like this comment if you guys are working on a collaboration @justinbieber." Since Bieber did in fact like the comment, that very well could mean that the two pop stars are indeed working on something together.

But that's not the only evidence that they might be collaborating. On Saturday (April 13), Bieber shared an Instagram highlight of Grande donning a sweater from his Drew clothing line.

This also wouldn't be the first time the pair have worked together. Grande and Bieber previously came together to work on the official remix for Bieber's "What Do You Mean." The two artists are also under the same management of Scooter Braun.

Braun also got in on the teasing of a potential collaboration, sharing an Instagram post on how grateful he was to work with Grande and Bieber. "We trusting you for a collab btw them," read one fan's comment on the post, to which Braun replied, "hmmmm."

Grande and Bieber have been friends for years, even dating back to their first red carpet photo together at Bieber's Never Say Never movie premiere in 2011.
