Lauren Graham and Peter Krause
Where they met: Parenthood. On this family drama she plays single mum Sarah Braverman, while he plays father-and-husband Adam Braverman — Sarah's brother. Eeeeew TV incest!
Did love blossom or bomb? Blossomed. Though the two kept their relationship under wraps for a while — presumably so as not to weird out audiences of their TV show — Lauren eventually revealed all in Redbook magazine. "It's so easy," she said of her union with Peter.
