Also, see this resolution:

Sometimes there are uncredited roles that aren't archival footage (particularly in post-credit scenes); would one of those count?

@ZaneMiller Nope, must be in the credits to count

This will Resolve YES if Taylor Swift has a credited acting role in the film, not merely if she’s on the soundtrack, or they uncredited archival footage of her (e.g. her shows, her music videos).

feel free taking my mana before answering but is there any reason to expect this?

@Bayesian Deadpool is extremely meta, and likes to joke about pop culture. The MCU’s on the decline in popularity, and Deadpool’s had stunt casting with Brad Pitt before and MCU’s stunt cast Harry Styles in a cameo.

So it wouldn’t be the strangest thing in the world.

@mattyb i'd add the strongest evidence it's even plausible is that swift is close friends with blake lively (ryan reynolds' wife), so there's at least a real connection there.

(but glancing at the article none of the evidence makes any sense so i'm a hard no lol)

Well the AI sure did make some art.
