Brad Paisley turned the wise old age of 40 this past Sunday (Oct. 28). And a very special someone gave him a very special birthday message, courtesy of the Grand Ole Opry.

Who was this someone? And what did message did they have for Brad?

You’ll simply have to watch the video for yourself and see.

Yes, that’s a special someone impersonating Marilyn’s infamous birthday song to JFK. And who is it? No, it’s not Carrie Underwood, Taylor Swift, Reba, Martina, or Miranda. Dolly Parton? Loretta Lynn? Wrong again.

It is, instead, one of the Opry’s most legendary performers–and someone whose sense of humor is a good match for Brad’s.

Watch the video below and see if you can make the connection.
