Smash star and Broadway vet Megan Hilty showed off her patriotic pride in Washington, D.C. on July 4 as the opening act on the PBS special A Capitol Fourth. Draped in a festive white and blue polka dot dress with a red belt cinching in her tiny waist, the Marilyn Monroe doppelganger helped celebrate the birthday of America by belting out a patriotic medley that included the classic tunes “I Want to Hear a Yankee Doodle Tune,” “God Bless America,” The Yankee Doodle Boy” and “You’re a Grand Old Flag.” Click below to watch Hilty’s firework-worthy performance!
