What are hd ??? ??two Taylor Swift fans who met at one of the pop star's concerts back in 2013 supposed to do when they want to spend the rest of their lives together?

Get engaged in the only way that made sense: In front of Taylor Swift herself.

During a meet-and-greet at her Reputation tour in Philadelphia on Friday, Swift shared a post to her Instagram joking how she was the third wheel after two Swifties decided to get engaged in front of her.

We're not sure who was more surprised and happier, Swift, or the bride-to-be, or the guy on his knee.

The couple, known only by their first names Anthony and Stephanie, said they met each other five years ago during Swift's Redtour.

Swift reportedly told Anthony he was a "baller," called the couple "incredible" and urged them to get married.

The proposal's been over a month in the making. Anthony made the Twitter account, @TSphilaPROPOSAL, in June in an attempt to catch Taylor's attention so she could witness him pop the question. In June, Anthony tweeted how special Swift was to bringing him closer to his bae:

He then tweeted how he wished for Swift to be witness to his proposal:
