Justin Bieber's comeback single "What Do You Mean?" is already a huge success, but if a new tweet is anything to go by, it could get even bigger.

The pop superstar wrote on Twitter that his forthcoming LP Purpose will be up for pre-order on Friday, October 16, and included a shoutout to Ariana Grande (with whom he shares superstar-manager Scooter Braun), along with the hashtag "#remix."

Since we've only heard one song off Purpose—excluding a banging snippet Bieber teased on Instagram on October 12, as well as "Where Are U Now," his collaboration with Skrillex and Diplo—the "#remix" likely refers to "What Do You Mean?" We can imagine Ari giving the female perspective and explaining what she (and all other women) mean when "you nod your head yes, but you want to say no."

While we stay waiting for this potential Bieber/Grande remix, check out everything else we know about Purpose -- which arrives on November 13 -- right here and then peep Ari's new blonde 'do on the just-revealed cover to her new single "Focus," coming on October 30.
