Is 'RHOBH' Star Kim Richards Drinking Again?

Now, we all know social gatherings between the lovely ladies of "The Real Housewives of Beverly Hills" don't always end well.

And Eileen Davidson's poker night on Tuesday night's episode was no exception.

It all started to go downhill while Kim Richards and Lisa Rinna were on their way to Eileen's shindig, and Kim started acting pretty strangely.

"What's wrong? You seem pissy," said Lisa Rinna on "The Real Housewives of Beverly Hills."

"I am just ornery," said Kim Richards.
"Really?" said Lisa.
"Yeah," said Kim.
"Are you drinking?" asked Lisa.

Kim said she was a little off because she was worried about her ex-husband Monty, who is battling cancer.

But Lisa later admitted in a confessional Kim's bizarre behavior made her call the housewife's sobriety into question.

Kim revealed she was battling alcoholism during "The Real Housewives of Beverly Hills'" season two finale in 2012.

Since then, it seemed like Kim had gotten her life back on track.

Heck, she was even getting along with Brandi Glanville, which we all know takes a lot of strength and a sound mind.

And that's why Tuesday night's episode took many viewers by surprise, including a writer for Bustle. "The moment was reminiscent of Kim's past erratic behavior before her sobriety, which is why it was so hard to watch."

Kim did admit to taking "something for the pain that the doctor gave her" before heading to poker night. It's unclear exactly what that was.
