Natalie Portman revealed her growing baby bump in body-hugging workout wear with a friend in NYC today. The actress is expecting her first child with fiance Benjamin Millepied very soon, and has been spending time at home on the East Coast as they await their new addition. The engaged pair did take a casual trip to the Hamptons over the weekend, but otherwise, Natalie has been keeping a relatively low profile since her busy Black Swan award season. At this point, it seems unlikely that she'll fly to LA for the May 2 premiere of her latest movie Thor. Instead, the best actress Oscar winner will probably stick to her routine of walking her dog Whiz and enjoying meals out with Benjamin ahead of her delivery, which is fast approaching.
