She even affectionately called Diana “Duch.”

According toTown & Country, they had a fairly complicated relationship.

Their mothers went to school together, so they knew each other growing up.

While the cousins were friendly in their youth, they didn’t become close until adulthood.

Diana thought Sarah could be a perfect match for her brother-in-law (viaInsider).

“They both enjoy practical jokes and like a good time without being complicated or envious.”

However, rumors began to swirl that Sarah and Diana were at odds with each other.

“But when their marriages collapsed they both had a shoulder to cry on.”

In an interview withHarper’s Bazaar, Sarah shared her side of the story.

“I never knew the reason, except that once Diana got something in her head … “And I knew she’d come back.

I want to talk to her.'

That interview took place in 2007.

“But everybody wanted [to see a feud] because we were so strong together.

People want to break something so strong.”
