Country star Taylor Swift, who's currently travelling the country on her '1989' world tour, helped two concert-goers make an incredibly special pregnancy announcement.

Jesse Rasmussen and his wife Lindsey, who are expecting their first child, met Swift during a media meet and greet and asked her to participate in sharing the big news, reported People Magazine.

The couple posted a picture on Twitter showing 25-year-old singer holding a sign that reads "Baby's 1st Concert," and the Rasmussen's stand on either side of the singer proudly showing off their ultrasounds.

"Thank you so much @taylorswift13 helping me tell the world IM GOING TO BE A DAD," Rasmussen wrote, sharing the image.

The father-to-be said after blurting out the plan to Swift, she was immediately on board. The couple has since used the photo to announce the pregnancy to friends and family.

The couple were even more surprised when they received a handwritten note from the Grammy winner a few days later. The card congratulated the couple and thanked them for sharing the big moment with her.
