• Martha Stewart getting lunch at the cafeteria of the National Museum of the American Indian on Monday afternoon. Long coat, comfy shoes. Posed for photos with the staff. We’re told that the lifestyle guru popped into town to catch the Hirshhorn’s Ai Weiwei exhibit before it closes this weekend (so you’d better hurry up, too); she also stopped off at the U.S. Botanic Garden. “A great day full of beautiful sights,” her rep told us. (Update, 11 a.m.: Stewart just posted an extensive photo blog of her Hirshhorn trip.)
