Justin Theroux Defines Happiness: Dogs and Jennifer Aniston

— -- Justin Theroux has fame, fortune and acclaim.

But when asked to define happiness, he went the sentimental route.

"My dogs," he told actress Amy Sedaris for Interview magazine. "And my lady, of course."

Theroux, 42, now starring in the HBO series "The Leftovers," is of course referring to his fiancée of nearly three years, actress Jennifer Aniston. In a recent interview, the actor noted that the two have "hot feet" about marriage, though he declined to say when they would wed. While speaking to Sedaris, he opened up a bit about the life he shares with Aniston, splitting time between New York City and Los Angeles.

"That's always been a goal, to be bicoastal in a real way," he explained. "The show is on a limited schedule. ... I'm writing during my long hiatuses and developing other stuff. It's a perfect fit. For someone who is scatterbrained like me, it's nice."

In addition to work (yes, he's developing a sequel to "Zoolander"), Theroux, whom Sedaris praised for always having a sense of style, is often found gallivanting around New York City or at the gym.

"I like to work out in the afternoon, around three or four. I just don't like to wake up and sweat. I'd rather have a cup of coffee," he explained. "In New York I used to just be more active. I'd always ride my bike everywhere or skateboard everywhere, walk, whatever. Then I started going to the gym."
