Is Kyle Richards's Rocky Relationship with Sister Kim on the Mend?

People.com:

Their relationship has been strained for some time, but Kyle Richards may finally be ready to make amends with Kim and put their bitter family feud behind them.

This weekend, Kyle captioned an Instagram post: "#NationalSiblingsDay these are my siblings @kathyhilton & @kimrichards11 #sisters no matter what …."

While Kim didn't respond to her sister's public message, the friendly photo is a far cry from their recent appearance on The Real Housewives of Beverly Hills reunion, where the pair went head to head.

"The way you act is just mean," said Kyle, 46, who asked if Kim, 50, was going to "disinvite" her to her daughter's wedding. "I want to have your children in my life." 

Kyle broke down in sobs and was nearly unable to continue: "You're so f---ing mean! Just leave me alone!"

While the reality stars continue with their back-and-forth drama, Kyle admits it's never been this bad between the two.

"I'm the first to say that my sister's and my relationship has obviously had its ups and downs, but this has by far been the worst place our relationship has ever been in," Kyle wrote in her Bravo blog post April 9.

"There seems to be no recollection of the love and support that I have given her throughout our lives."
