Lauren Graham and Peter Krause, Parenthood
The two eldest Braverman siblings have been dating in real life since reconnecting on the NBC drama in 2010. Graham and Krause first met in 1995 when they both guest-starred on Caroline in the City. "It was just a funny timing thing," Graham told More. "We were friendly. But our lives went in separate directions. I would see him now and again. It wasn't like I thought, 'Oh, someday.'"
