Taylor didn't just pick up a generic Deadpool costume, either. It seems Ryan himself hooked her up with an ACTUAL costume from set.
So yeah. She basically went as Ryan Reynolds.
The 26-year-old captioned one of three Instagram photos,
Yup. No other Deadpool costume could have been as badass as hers this year.
As usual, Taylor was completely isolated on Halloween night and only uploaded selfies of herself hanging out alone with no one else around.
No, I'm kidding. She always rolls deep.
She actually dedicated not one, but two Instagram photos to showing off her squad's solid Halloween costumes.
I don't get FOMO easily, but her squad shots always give me a little twinge.
I feel the same way about Taylor's squad as she does about Ryan and Blake's relationship. Sigh.
OK, but wait, we haven't talked about the best part of this "Deadpool" Taylor Swift situation.
Blake Lively saw these photos and couldn't resist making this hilarious comment.
Funny, Blake, but let's be real. You're already married to Ryan Reynolds. How can you really top that?!
This isn't the first time this weird little friendship triangle expressed their love for each other on social media.
Last week, Ryan posted a sweet photo of himself and Blake at his birthday dinner, which made Taylor "[drown] in tears of joy."
But can you blame her?! I'm telling you. If there was an award for the cutest celebrity couple, they'd win for sure.
