Why pick her? Pick Lauren Jauregui since she can actually sing.
Camila is her friend
Also tbh, Camila is the most popular member and we all know that, so I agree that in a solo career she is the only one with a chance
Misleading title. Taylor didn't "plan" their duet. Taylor is the one who brought them to 1989 and from that Camila and Shawn met, eventually led both of them to a write song in her backstage. If it weren't for Taylor's tour invitation, they wouldn't have spent time together to write this song.
