A very-pregnant Natalie Portman was spotted leaving Square One restaurant in Silverlake, CA, this afternoon. She went casual for the lunch outing after dressing up in a gorgeous white gown for Sunday's Screen Actors Guild Awards. Natalie picked up the best actress statue for Black Swan and once again thanked her fiancé and choreographer, Benjamin Millepied, in her acceptance speech. Benjamin's had his own share of the spotlight since the film has received so much attention during award season and his career and fame were chronicled in a NY Times spotlight this week. Natalie has said that her baby is due late this Spring or early Summer, but we're thinking he or she may be coming sooner!
