The above linked article talks about a photo shoot from 2017 that Barbie did with Aimee Song’s doll. According the the article, Mattel says that Barbie is queer when it authorized the photo shoot. I don’t disagree that Barbie might not be only into Ken, but, really, it seems that Twitter and memes are the ones who declared her sexuality, and not Mattel.
The photos are fun, and so are the comments, but I am not sure that it was authorized by Mattel.
Barbie was not available for comment.
