In the pic, the parents-to-be pose on either side of an LBD-clad Swift, with mom and dad each holding an ultrasound pic. In the middle, Swift wears an excited and surprised-looking smile, while holding a sheet of paper that reads, "Baby's 1st concert!"
Jesse captioned the photo: "Thank you so much @taylorswift13 helping me tell the world IM GOING TO BE A DAD! #BabiesFirstConcert @lindseyjo86."
As if that's not cool enough, the "Shake it Off" singer also followed up with a handwritten personal note of congratulations, which dad also shared on social media.
While Swift is well known to interact warmly and personally with her fans, she's not the first celeb to help ordinary folks announce their pregnancies. Kelly Clarkson, Will Smith, Paul Rudd, and Vanilla Ice are all among those who have gotten in on the fun!
