The French femme fatale and the most famous playboy of the day seemed to have been made for each other. In 1966, Sachs, the German son of an industrialist, showered the famous blonde actress and singer with 1,000 red roses in a dramatic marriage proposal. Though the couple divorced after just three years, the romantic gesture remains legendary.

It was an arranged marriage, but Queen Victoria quickly fell head over heels for her husband, Albert. The couple was inseparable up until Albert's death in 1861. A decade later, Victoria commemorated her partner by opening a concert hall in his name, the world-renowned Royal Albert Hall in London. This family portrait was painted in 1846.

Ken Morgan was a former bus driver and Shirley Morgan had been a conductor. They met over 61 years ago in a double-decker bus in England and it was love at first sight. They are still married after all these years - and still seem to be very much in love. As a sign of his affection, Ken presented Shirley with an unusual gift: He bought the bright red bus they had first met on.

The tears streaming down the cheeks of the Irish singer will give you goose bumps. In the 1989 video "Nothing Compares to You," she sings about a lost love - one of the most emotional declarations of love in music history. The tears at the end of the video are real, O'Connor has often maintained - although they weren't shed for a man but for her deceased mother.

In the comedy-drama by director Roberto Benigni, Italian Jew Guido and his wife and son are deported to a Nazi concentration camp and separated. His declaration of love for his wife Dora at the end of the film moved millions of viewers to tears. Over the loudspeakers at the camp, he said goodbye to his "principessa," sending her a message of hope. Pictured above is the German film poster.
