Walker Hayes and Wife Laney Are Expecting Baby No. 4

Country music newcomer Walker Hayes and his wife, Laney, will need to invest in a mini-van soon if they haven't already, as Hayes announced via his Facebook page that the couple is expecting their fourth child.

"Laney plus walker equals baby number four on the way," the singer said Monday, Jan. 17.

Hayes' debut single, 'Pants,' premiered at No. 60 on the Billboard Hot Country Songs chart when it popped in September, and the music video was released just before the end of the year. 'Pants' is a joke about who is in charge in the couple's ever-growing household. "She is so much better than me at so many things — for example, parenting our kids — and I will bow down and cower to whatever she says," he admits on his site. "She does wear the pants and I’m OK with that, as long as I can take them off her."

We wonder if that means he's on diaper duty when the little one comes!
