Christo and Jeanne-Claude

What is love, but a collaboration?

Christo and Jeanne-Claude - "It was love at first sight. Discovering that they were both born on the same day, 13 June 1935, they took it as a good omen. Everything happened very quickly. Jeanne-Claude changed the lock on her apartment, separated from her husband telling him, "Your key no longer fits my lock," and left him to spend her life with Christo." -excerpt from Love, by Florence Montreynaud
