Jennifer Aniston and Justin Theroux are the proud parents of a baby girl! The couple of nearly a year now share massive homes in Bel-Air and in downtown Manhattan -- and, to seal the deal, have adopted a puppy named Sophie, Theroux, 40, tells New York magazine.
"She's the most adorable little cookie you've ever seen," the actor-screenwriter says of Sophie, a 3-month-old boxer-pitbull mix. "She looks like she just smoked an exploding cigar."
Theroux and Aniston, 43, became romantic shooting Wanderlust in Georgia last fall, but the actor remains reluctant to open up about the relationship.
"I understand the curiosity, but other than saying I am happy, I am not going to indulge it," he tells the mag. "That's building your own torture device."
Of his increased celebrity as beau to one of the most famous women in the world? "[It's like] having shoes that are slightly too heavy—it can slow you down and make you more cautious," he says.
In Wanderlust, Theroux stars opposite onscreen couple Aniston and Paul Rudd, playing Seth, the leader of a free-love commune in rural Georgia.
"I was thinking of him as a David Koresh–type figure, a comic cult leader who is so sincere in his insincerity," Theroux says of the role. "It's hard to play that douche-y a guy without cracking yourself up."
