They say after you eat Chinese food, you're hungry again 10 minutes later and want seconds.
This couldn't be more dead-on than in the case of actress Drew Barrymore and her second pregnancy.
"Oh, my God, I'm eating everything! I can't get enough of Chinese food. It's all I want to eat!" she told People magazine. "I'm feeling very, very happy."
A mouth full of fried rice will do that to you.
Word broke Monday of Barrymore's second pregnancy with husband Will Kopelman. It wasn't too much of a surprise because the "ET" star, 38, had expressed her desire to give her 13-month-old daughter, Oliv,e a sibling, especially growing up an only child and admitting "it was lonely."
"Will is just thrilled - we both are - [because] we just wanted so badly for Olive to have a sibling," she told People. "In some ways, it's really for her. So congratulations, Olive!"
