Kim Richards On Bitter Feud With Sister Kyle: 'The Hurt Won't Ever Really Go Away'

On an emotional episode of Watch What Happens Live, Kim Richards reveals new secrets behind her tumultuous relationship with sister Kyle.

"The hurt won't ever really go away," the 51-year-old told show host Andy Cohen of their epic feud on Tuesday.

"There's certain things she's done towards me that I personally have to put aside if I want to move forward," Kim continued. "She called and reached out to me and I wasn't ready. So I said to her, 'I have to put those things aside and if you want to move forward, that's what you need to do too.'"

Later, the reality star also got candid on her sobriety.

"The last time I shared my recovery with the world, that it became no longer mine. It was the public's," Kim said. "So this time, in my recovery, I've decided to keep it for myself."

As RadarOnline.com reported, Richards claims she's been able to stay away from substance abuse after her scandalous arrests last year, telling Entertainment Tonight: "My recovery is going amazing."

The reality star is getting back into TV as well, making guest appearances on her old show, The Real Housewives of Beverly Hills, and the dramatic Mother/Daughter Experiment: Celebrity Edition.
