At first glance it looks country—a traditional brick facade with a coat of grey paint. But walk through the grand double front doors of Joe Don Rooney's Tennessee spread, and it's an unexpected sleek oasis: "very un-Nashville," says the Rascal Flatts guitarist of the home he shares with his wife, Tiffany Fallon, and their 16-month-old son Jagger. "Classy casual."

For Rooney, 34, and Fallon, 35, a Playboy Playmate of the Year and former Miss Georgia, the 6,000-sq.-ft., four-bedroom abode in a gated golf-course community outside Nashville is the perfect mix of urban and rural. "I love the dichotomy of the city-country family," says Rooney. "You know, drive down the road to Target and see cows and horses on the way." It also gives Rooney a peaceful sanctuary to shake off the pressures of the road. "It's my landing pad," he says. "I come home and leave it at the front door."

The couple, together six years and married for three and a half, are like "sugar and spice," says Rooney. "She's the spice." And since welcoming Jagger into their lives in May 2008, they've only grown closer. "I love her; I've always loved her drive and her zeal for life, but to see her be a great mom is the most magical thing. She's such a devoted mother." Becoming parents may have been a bit of a surprise—"We weren't expecting it," admits Rooney—but it's a role they've both embraced. "He has become selfless," says Fallon of her husband. "He always wants to give Jagger a bath or read to him. I'll say, 'Hey, would you mind taking hold of Jagger for a quick minute?' and it ends up being two hours, and he never complains about it. Never."

When Rascal Flatts is on tour, Rooney usually spends the early part of the week at home, then flies out on Thursdays for weekend shows. "He probably gets to spend more time with Jagger than a person with a 9-to-5 job would," says Fallon. Most days, that means having breakfast in their eat-in kitchen or watching The Today Show in the family room. "We're pretty unglamorous when it comes to being home," says Rooney. Afterward Rooney retreats to the lower level, affectionately known as "Man Land," which comes complete with pool table, bar and state-of-the-art recording studio. "Tiff let me go crazy with it," he says. "I'm a techie geek. We've got wifi everywhere so I can hook up my guitar with this belt pack and play anywhere in the house." "Ten at night, and I'm like, 'You really have to turn that down,' " says Fallon with a laugh. "I'm like, 'We have a kid, remember?' "
