Denise Richards Didn't Accept Lisa Rinna's Excuse For Lashing Out; Calls Former 'RHOBH' Co-Star 'Cruel'

Denise Richards wasn't moved by Lisa Rinna's emotional apology in the recent episode of "Real Housewives of Beverly Hills."

Richards, 51, took to Instagram Thursday to weigh in on the episode where Rinna was emotional while apologizing for her behavior toward her co-stars, explaining that she was grieving due to her mother's passing. But the former "RHOBH" star wasn't having any of it.

"I watched #RHOBH last night. While I have empathy for Lisa Rinna losing her mom. What is her excuse all the other years on the show for being so cruel & so vindictive?" the "Drop Dead Gorgeous" actress wrote.

"RHOBH" co-star Garcelle Beauvais seemingly agreed by liking the post. Several netizens also agreed with Richards.

"She has zero excuse, she does this season after season and then apologizes at the reunion," one wrote.

"Totally agree! She's can dish it out but can't take it. I can't stand when she presses People to be accountable. She's never accountable for her own actions even after you all apologize she goes add it and add it and add it. She should take a break," another wrote.

"I used to like her but cannot stand watching her & the mean girls club anymore. I wish they would just get rid of her & that group," a different user added.

Meanwhile, several netizens hoped Richards would return to the Bravo reality show.

"COME BACK!!!," Kiki Monique commented. Mrs. Hammy added, "We want to see you back on the show!"

"Exactly!! You need to come back and call her out," a third person wrote.

In the reunion special, Rinna apologized for her "disastrous" behavior. Footage of her outburst at her fellow castmates, including Sutton Stracke, was aired. There was also a scene where Rinna said goodbye to her mom, Lois, who passed away in November.

"It's hard," Rinna told host Andy Cohen while in tears, ET Canada reported. "It's really hard to come into a show like this, and maybe would've been better if I had taken the time off."

She continued, "When you're in that deep of pain — I've done the best I can. I'm sorry for being crazy and a maniac and screaming and doing what I've done. I'm really just trying to walk through life."

Rinna waited almost a year to put her mom to rest after her passing because it was the latter's wish to be buried in the summer. She said things were confusing, and she was all over the place.

Stracke confronted Rinna for the latter's outbursts toward her. She reminded the Rinna Beauty founder that they talked a lot of times when Rinna's mother was in hospice and after her passing.

"So, when I'm getting yelled at over and over and over, I'm thinking, does she not remember that I was such a good, steady friend to you? You yelled at me a lot. I was a dead horse," Stracke said, adding that "I really need an apology."

"I am sorry that I did that, I really am," Rinna responded.

"I understand that, but I'm talking to you now and I am sorry that I took it out on you. I am sorry that I took out my pain, anger, sadness and fear out on you. I understand you'll accept it if you want or not, but I want you to know that I am sorry that I took it out on you, 'cause I did. And I am sorry."

Stacke thanked Rinna for apologizing to her. Rinna also spoke to ET at BravCon over the weekend and said they "care about each other" even if it doesn't come across onscreen.
