Katherine's 28th Dress

Katherine Heigl got dolled up and exuded some old-school Hollywood glamor as she donned a red satin dress for her appearance on last night's "Late Show with David Letterman." The actress, on the promotional tour for her new rom-com "27 Dresses," kept warm under a white coat as she greeted fans who gathered outside New York's famed Ed Sullivan Theater for the show's taping. Katherine should really embrace this old Hollywood look  - then she'd have an excuse to smoke her beloved ciggies - Bette Davis was never without one!
