Between getting recently engaged, crying constantly on the set due to Margene's "big secret," and wrapping the final season of Big Love—Ginnifer Goodwin has been crying a lot lately. Here's why.

Later, she told stories of how well the Big Love cast got along and teased the show's fifth season. Apparently, Margene has a gigantic secret that will play a major storyline in the show's final season. As she put it, "you don't find out that Margene was a man—but it's that kind of big."

Big Love returns for it's fifth and final season tomorrow night on HBO.
