Stopping to talk to ET's Nischelle Turner at the premiere of Disney's new live-action adventure epic "Tomorrowland," it was clear that sparks were still flying fast between the 48-year-old musician and his 47-year-old country star wife Faith Hill.
Things got racy when Nischelle complimented Hill's gorgeous gown.
"You know the best part about this outfit is that I get to unzip it," McGraw said, smiling. "Tonight."
When Hill playfully smacked him, and reminded him that they were at a Disney premiere, McGraw laughed.
"How do you think those little kids got to be running around?" McGraw joked. "I mean come on!"
Speaking of kids, Hill also opened up about her family's plans for Mother's Day,
"Honestly I feel like it's mother's day every day, truthfully, just to be all together," Hill said, adding, "and you know, I don't have to cook. So that's nice."
