The first time Kimberly Williams-Paisley left her country star husband in charge of their son Huck, she was, he recalls, a nervous mother.
“She was going away to do a press thing in New York, and she gave me this list of things to do like: ‘No gluten, make sure he takes his nap, don’t let him watch TV,’ ” Brad Paisley says of the care needs of the now 3-year-old. So, he did what any caring husband would do: He punk’d his wife.
“We no sooner had a ‘coast is clear’ kind of situation, [then my band and I] went and bought a doll at Toys ‘R Us – a life-size, most realistic doll we could find – and dressed it up in the same clothes [as Huck] and filmed,” says the practical jokester, known for pranking tour mates Taylor Swift and Kellie Pickler.
