Michael Douglas-Catherine Zeta Jones

It was truly a 'Cheeni Kum' moment when, in Y2K, a 56-year-old Michael Douglas knelt before a 31-year-old Catherine Zeta Jones with that now-famous proposal line, "I want to father your children". Cassandras predicted the marriage to last for not more than a year. They were proved wrong.

However, the 12-year-old marriage has braved more than its share of challenges including Michael's encounter with cancer and Catherine's battle with bipolar disorder. But the couple has, in spite of the challenges and an age gap of precisely 25 years, managed to stay together and in love.

Here is a pictorial tribute to Michael and Catherine, the Pair Perfect of Hollywood.
