Last February, when Taylor Swift's Fearless tour swept through Detroit at the Palace of Auburn Hills, she hosted her nightly T-Party backstage for the local radio stations as a thank you for supporting her career over the years. As Swift worked the room and spoke with the staff one-on-one, she took a liking to 99.5 WYCD's Jason 'the 300lb Cowboy' and his girlfriend, Kelli. Before the night came to an end, Swift's mother warned the happy couple, "Next time I see you two, you'd better be engaged!"

Well last Thursday, July 28, Swift made her way back through the area on her current Speak Now tour, stopping in at the Van Andel Arena in Grand Rapids. Though the 'Love Story' singer was none the wiser, Swift's record label rep, Jack Purcell, was well aware that Jason was considering using the night to pop the question to Kelli in front of the singer and her mother.

Once Swift entered the room, she mingled with the station staff. When she and her and mom made their way to Jason and Kelli, they hugged and spent the next few minutes catching up. It was then that Jason reached into his pocket and pulled out a ring for his unsuspecting girlfriend!

"The last time we saw you, you told us we’d better be engaged the next you saw us, so Kelli..." Jason said, according to the radio station's website. A shocked Swift helped make sure it was the picture-perfect proposal by urging the radio host, "Get down on your knee!"

Jason then dropped to his knee and proposed to Kelli, who obviously said yes. No word yet on whether Jason and Kelli will ask Swift to be their wedding singer, but they definitely have the proposal story of a lifetime to share for many years to come! Congrats to the happy couple!
