Meet Brad and Kimberly Williams-Paisley‘s second son, Jasper Warren!

Although the country star and his actress wife chose to wait for a delivery surprise when expecting elder son William ‘Huck’ Huckleberry, 2 ½, “for the second one, I wanted to plan,” Kim says. The couple were “thrilled” to discover they were having another boy.

During her pregnancy, Kim “winged it a little more and trusted my instincts. I was more easygoing with Jasper, and he’s more easygoing too.”

So much so that Jasper, now 4 ½ months, made his entrance into the world almost two weeks late, finally arriving April 17th in Nashville.
