Yep! We don’t need any more confirmation than this post from Dan + Shay, the caption reads: 

“Hey Pittsburgh/Greensburg! We will be performing on an upcoming episode of @bacheloretteabc! RSVP to attend: thebachelorRSVP@gmail.com More details in comments…”

The guys just invited their fans to be part of the taping. Must be one of those Bachelorette dates where they have the guys serenading the couple, which we’ve seen before. What a lucky Bachelorette and talk about spoilers!
