Kevin Dillon's Entourage

Kevin Dillon's Malibu home contains a few touches worthy of his Entourage alter ego, Johnny "Drama" Chase: a new set of weights on the patio where he can catch sun while pumping iron; a foosball table in the guesthouse (where big brother actor Matt sometimes stays when he's in town); and his self-described "man cave"—a garage he converted into a tricked-out home theater with a state-of-the-art golf simulator. But as the 43-year-old actor ambles through his three-bedroom, Mediterranean-style house, he steps over toys scattered on the living room floor, points to flower beds pulverized by bulldog pups Brady and Belle, and shows off a kitchen where he serves up soufflés. "Stiff peaks on the egg whites," he notes. "Very important."

After a career that included early big-screen successes like Platoon and The Doors, Dillon spent a stretch better known as "Matt's brother." Now he's a two-time Emmy nominee, a costar of the family comedy Hotel for Dogs—and a down-to-earth dad who brags not about conquests but baking prowess. His real-life entourage consists of wife Jane Stuart, 30, their daughter Ava, 2, and Amy, his 18-year-old daughter from a previous relationship (she lives on the East Coast but visits often). "I'm not a kid anymore," says Dillon, who is more likely to be found wielding clubs—he's a golf fanatic—than partying in them. "I feel like I've done it all, so there's nothing really more for me to do in that department. I want to enjoy the days."

To that end the Mamaroneck, N.Y., native has made his home a sanctuary from the Hollywood hoopla portrayed in the HBO series that put him back on the celebrity map. "We just fell in love with it," he says of the house he bought about two years ago. Since then he's devoted himself to projects like landscaping a lush yard (where the oranges and lemons, he laments, fall faster than he can eat them) and tending to his 125-gallon coral reef tank ("my baby," he calls it). Domestic bliss is shared with Stuart, a Scottish former model he met through a friend in 2004 and wed in April '06 (with Entourage pals Kevin Connolly and Jerry Ferrara looking on), and Ava, who arrived a month later. "When she was born, he cried like a baby," says Stuart. "He's got a very big heart."

Still "really close" to his family—parents Paul and Mary Ellen, a sister and four brothers, including Matt, 44—Dillon says he'd like to expand his brood: "I hope so—I always thought I'd have thousands." For now, as he prepares to start shooting the show's sixth season in March, he's content to focus on fallen soufflés, scraped knees and everyday dramas. "Life is good," he says. "I'm a lucky guy."
