Pictures of Pregnant Evan Rachel Wood on Set

Evan Rachel Wood got to work filming 10 Things I Hate About Life in Malibu this week. She was in front of the cameras with her leading man Thomas McDonell on Monday and again on Tuesday, when she showed off her growing stomach in between takes. Evan announced her pregnancy today and shared on Twitter that she and husband Jamie Bell "are very happy. I'm gonna be a mama!" Evan and Jamie got married in October, surprising fans with the news a few days after their CA nuptials.

It's an exciting time for the couple, who on top of impending parenthood, both have multiple projects in the works. Evan's current movie won't be released until 2014, but she has many others coming out this year, including The Necessary Death of Charlie Countryman with Shia LaBeouf, who also stars alongside Jamie in Nymphomaniac.
