-During an interview Chris said he'd be open to working with Zayn because he's his "homeboy" and they're on the same label
-Chris also said he'd want to collab with Zayn because he has a huge fanbase and fans are waiting to hear his music
-Chris also made note that he's not very selective about who he works with because he's on everyone's songs.
-Zayn has yet to comment, though he has shown appreciation for Chris' music in the past. His fans are also very eager for the collaboration to happen.
I think this collab is def going to happen, like Chris said he isn't too selective and it'd be the easiest way to get him some cred.
