January Jones flipped out at the 'Mad Men' Betty Draper plot twist, too.

So about that Mad Men episode.

The one in which Betty Draper Francis finds out she has terminal lung cancer and refuses to be treated for it.

We caught up with January Jones, who played Betty on the AMC series, at Monday's rainy CFDA fashion awards.

Really, now, that was one doozie of an episode, and finale.

"It's airing affected me in a way I didn’t expect," she said.

So did the finale.

"I wept like a baby for two hours and I was not expecting it at all. I’d said goodbye in July. I skipped the viewing party. I watched it alone with my sister at home and I’m glad that I did. It was hard. It was really hard. It was the end, for real."
