Blonde bombshell Marilyn Monroe was at the height of her Hollywood acclaim when she married playwright Arthur Miller, her third husband, in 1956. It was an unexpected union, to be sure, provoking headlines like "Egghead Weds Hourglass." Despite the skeptical press, this new role was one Monroe relished, and she fled Los Angeles for a year and a half to devote herself to married life in New York City. In 1958, LIFE photographer Robert W. Kelley documented a night with the Millers, capturing the couple in their midtown Manhattan apartment as they hosted theater producer Kermit Bloomgarden.
