Justin Bieber is ensuring everyone knows about his upcoming single "What Do You Mean" by getting a slew of superstar friends to hype up the track. So far, the likes of Ariana GrandeMariah CareyLittle MixHalsey, and Shaquille O'Neal have shown their support with selfies counting down the days to the new song's release.

Ed Sheeran is up next, but the "Growing Up" singer went the extra mile and played an acoustic little clip of what very well might preview the new tune's melody and lyrics on Instagram. Eddie sings in his signature crooning style, "What do you mean? / Said you're running out of time / What do you mean? / 17 days' time." Watch below:

There's very little info about "What Do You Mean," but Bieber said it's "uptempo," while USA Today got an early listen and described it as a "catchy dance track for the club." The paper also revealed part of the lyrics—"What do you mean? / You don't want me to move, but you tell me to go / What do you mean? / You nod your head yes, but you wanna say no"—and Ed's lyrics follow the same structure.

We've got less than three weeks to go until "What Do You Mean." In the meantime, check out everything we know about Bieber's upcoming album right here.
