Joanne Woodward and Paul Newman – 50 years
Like many other actors, these two actors met on the set in 1953 while performing Picnic on Broadway. It was only later when they fell in love and started dating after they starred in the movie The Long Hot Summer.
They married on January 29, 1958, and they have three daughters together (Newman already had 3 children from the previous marriage with Jaqueline Witte). Their happy marriage lasted for 50 years until Paul Newman died in 2008.
