"We dig being together all the time. Both of us could survive apart but what for?"
The following photos capture some of history's most captivating couples when they were young and head over heels in love.
Some went onto have life-long and happy relationships, others fizzled out in a blaze of drama and recriminations.
But in this one moment, they are besotted with one other. Their body language speaks of a kind of chemistry that's so intense, everything else becomes background noise.
From the lustful magnetism of Jane Birkin and Serge Gainsbourg to fiery creative passion of Frida Kahlo and Diego Rivera and the sweet grungy romance of Johnny Depp and Kate Moss, come remind yourself of the stories behind some of history's most beguiling and love-up couples.
Jane Birkin and Serge Gainsbourg (August 1969)
The story: It was love at first sight when Jane Birkin met Serge Gainsbourg on a film set in 1968, sparking a passionate and unique 12-year affair made infamous by their erotic duet Je t'aime... Moi Non Plus (a song that hit the big-time after it was banned by the Pope).
She says: "When I gave birth to our daughter Charlotte in 1971, Serge said it was the happiest night of his life. He wanted us to marry, but I’d been married to John [Barry, the composer] and that was enough. Now I regret turning Serge down."

How did it end? Both artists had affairs and they divorced and re-married again in the same year (1940). Frida died aged 47 in 1954, possibly from an overdose.

The story: One of Hollywood's most enduring love stories began on-set The Long Hot Summer in 1957. Paul and Joanne tied the knot one year later in Las Vegas, and weathered 50 years of marriage, through the creative differences of working together and the drug overdose death of Paul's son (Joanne's stepson) Scott.
She says: "From the beginning, Paul and I had an advantage: we were good friends before we were lovers. I mean, we really liked each other. We could talk to each other. We could talk to each other, we could tell each other anything without fear of ridicule or rejection. There was trust."
How did it end? They had three children together (along with Paul's three children from his previous marriage) and lived in Connecticut, attributing their happy marriage to patience and affection. Soon after they celebrated their 50th anniversary in 2008, Paul died of lung cancer aged 83.

How did it end? With a $113 million (£71 million) lawsuit filed by Scott in 1982 - the first same-sex palimony case filed in US history.
