It really does help when your BFF is his wife.

Taylor Swift showed off the costumes and fun her crew had this Halloween with several Instagram posts today, the highlight of which was her own Deadpool costume in what appears to be the most fully legit Deadpool costume besides the one Ryan Reynold's wears himself in the film. 

And there's a reason why.

Turns out Swift got some help from the "inside contact" so it's safe to say her outfit, if not one of a kind, was very rare indeed.

Taylor thanked Reynold's in one of her many photos of the night that she shared, saying in one: "Thanks @vancityreynolds for this costume, you're the BEST deadpool inside contact ever." 

Swift's squad for the evening included Gigi Hadid as a Cub Scout, model Kennedy Rayé as a cat, Lily Donaldson as a space cadet, Emmie Gundler as a black swan, Camila Cabello as a grandmother looking for her lost cat, and Victoria's Secret model Martha Hunt as Marcia Brady.

Here's hoping she gave it back to Fox/Marvel/Reynold's so that they can all get going on 'Deadpool 2'.
