"We stayed up late one night a couple years ago and I think we had too many drinks. Maren said, 'What would you name a boy if you had one?' and I was like, 'I always thought the name Hayes was cool,'" Hurd said. "And she remembered it."
As for Hayes' middle name, Hurd revealed that Andrew is his late little brother's name.
"That was a really cool way to honor him and my family," Hurd said.
