Costars on True Blood and in real life, Anna Paquin and hubby Stephen Moyer shared a relaxed – and romantic – steak and shrimp dinner at Boa Steakhouse in Santa Monica. "They were really sweet with each, taking turns and trying both entrees," an onlooker says. Adds the onlooker: "When they weren't eating, they were holding hands and leaning into each other and talking."
