We look at some celebrity couples old and new who gave themselves the best possible chance of living in eternal matrimony – at least according to new research.
New research has revealed the ideal age to get married, with sociologist Nicholas H. Wolfinger of the University of Utah finding that couples who get married in their late-20s and early-30s to be at the lowest risk of separating.
What better way to test these findings than applying them to the world of celebrity couples? Here are some famous couples who lend credence to the findings, and others who research suggests are destined to go the distance.
Kim and Kanye
Kim and Kanye, the great romance of modern times, were 33 and 37 when they celebrated their love with an extravagant French wedding last year, meaning they just squeeze into the low-divorce-risk sweet spot.
