No one knew for sure if Maria Shriver would show up for Oprah's farewell extravaganza last week so soon after news broke about her husband's infidelity, but she did, and for good reason: Maria refuses to hide.

"She's done nothing wrong, but even so I'm surprised she has had enough courage to go out in public," a friend of Maria's tells me. "When this happens, most women want the world to swallow them up. They want to stay home behind closed doors, but not Maria."
