Evan Rachel Wood is craving . . . cannabis? The pregnant Mildred Pierce actress tweeted about her food frustrations on Tuesday, July 9. "Whoa. Whoa. Peanut Butter Pop Tarts?! Of course, because I can't smoke any weed right now," she wrote. "Dammit!"

Whether she was kidding or not remains to be seen. Wood has, however, tweeted multiple times about the joys -- and pains -- of pregnancy. "How can you be so excited to see someone you have never even met?" she asked her followers on July 6. Six days later, she joked, "When a pregnant woman says she just 'rolled' out of bed, she is being very serious."

Wood, 25, also admitted that "sometimes" her diet "goes to hell" and she has "pigs and a blanket and a pizza" as she awaits the arrival of her firstborn child with husband Jamie Bell. "You gotta have your naughty days," she tweeted July 6.

In January, a rep for Wood exclusively confirmed the actress' pregnancy to Us Weekly. Months later, the mom-to-be told Us she had been craving "pickled onions." She also admitted that her wardrobe required a makeover.

"Pants are just out the window," she said with a laugh. "I got all these maternity pants and I was just like, 'No.' So it's dresses, which are kind of different for me. Pants are gone."

Wood and Bell tied the knot in California on Oct. 30, 2012.
