Brad Paisley experienced a “first” on-stage this past weekend. While performing in St. Louis, a couple had a sign that read, “He or She? Brad will you tell me.”

The couple, Monica and Kyle Thayer, joined Paisley on stage so he could reveal to them, and thousands of others, the gender of their baby. The envelope was sealed up tight, but once Brad managed to get it opened, he shared the exciting news that the happy couple is expecting a baby boy.

After the show, Paisley tweeted, “Okay, the baby gender reveal thingy tonight in St. Louis was about the coolest thing ever. We’ve got video of it, we’ll post it in a bit.”

What a memorable experience for Monica and Kyle Thayer, as well as Brad Paisley and all the fans that witnessed the exciting moment!
