Fans are convinced a snippet of "Bad Blood (Taylor's Version)" features in the Super-Pets trailer

The trailer for DC League of Super-Pets sees Superman's dog Krypto - voiced by Dwayne Johnson - get annoyed with Superman for having a date on the same day as The Great British Bake Off season finale, leading the dog to put on headphones and chew Superman's boot while a clip of Taylor Swift's "Bad Blood" plays.

Fans are convinced that the snippet of Swift's 1989 track is the upcoming re-recorded version, which could be possible as Swift already released "Wildest Dreams (Taylor's Version)" in September.

One fan wrote, "Warner bros we need to know if you are ethically sourcing your taylor swift. Is this Taylor’s Version?" Another fan responded, "The old versions cannot be used without Taylors approval, so its def the new version."
