Natalie, Claire, J Lo and Eva in the House

A casually chic Natalie Portman showed up at Derek Lam and Rodarte. The incredibly shrinking Claire Danes (does she weigh more than 80 pounds?) was the Hollywood heavyweight at Zac Posen’s show.

Jennifer Lopez lent her star power to Oscar de la Renta’s audience, while Eva Mendes smoldered from her perch off Calvin Klein’s runway.
