Christopher Schwarzenegger, 24, linked arms with mom Maria Shriver, 66, on Wednesday in New York City, showing his dramatic weight loss as the two strolled through the Big Apple. Maria sported a long, plush pink coat and black, knee-high leather boots while Christopher displayed his slimmed down figure in a black zip-up jacket, light grey chinos, and white sneakers. The mother-son duo were all smiles as the paparazzi snapped some photos during their night out together.
