They may have split, but Jake Gyllenhaal
and Reese Witherspoon
agree about one thing: They both still like Lamill, a coffee house in Los Angeles's Silver Lake neighborhood. On Sundsay, the actor brought his dog Atticus to meet a friend for coffee on the patio, while Witherspoon brought her kids Deacon, 6, and Ava, 10, the next day to have lunch with a girlfriend. "They were sitting inside, eating, laughing over lunch," an onlooker said, "It looked she's a doting mom who didn't have a care in the world."
