Blake Lively, Ryan Reynolds and Jesse Tyler Ferguson also weighed in.

"If God ain't want me to run on stage... he wouldn't have sat me in the front row."

See how Taylor Swift and more reacted to the news.

This would be an EPIC collaboration.

The business owner was understandably frustrated by the striking comparison.

Fans are absolutely convinced this is yet another one of Swift's hidden Easter eggs.
