The mother-of-three replied, “I don’t wanna eat that stuff. I’ve smoked weed twice in my life, and I’m good. I’m not gonna say who I did that with,” while looking at the camera and giving a wink.
Throughout the night, Denise, 52, continued to make strange faces and winked as she shared her hot takes with the group.
When Kyle and Sutton Stracke were late to arrive at the table, Denise wondered, “Did she have too much of the hors d’oeuvres?” adding, “Well, you know what I’m talking about.”
Throughout the conversation, the former wife of Charlie Sheen was bizarrely quiet and often nodded slowly or opened her mouth with a blank stare.
Fans then took to X, formerly known as Twitter, where they trolled the star for her abnormal behavior.
“Why was Denise Richards acting like.. that,” one user said, while a second speculated, “Y'all can't tell me Denise Richards isn't high on... something.”

“Was Denise Richards on something last night? No offense, she just seemed wayyy too out of it,” another tweeted, as a fourth added, “Denise Richards was a HOT F------ MESS tonight.”
Another user wrote, “I love Denise Richards… but my sis looks CRAZY,” while a fifth noted, “What is up with Denise and all of these faces she’s making?”
Others loved the entertainment value Denise brought to the episode, saying, “I think it’s safe to assume that Denise Richards got her pre-party on. I’m fully here for it though,” while another viewer quipped, “Denise is on another planet."
As OK! previously reported, Denise has always been a little different than her fellow Housewives, as she was known to dress down on the show despite her costars often dressing up.

"I loved seeing what outfit Dorit [Kemsley] was going to show up in. That is not who I am. I do that for an event because for me, it's work. Dorit said, 'This is work.' I said, 'I didn't think of it that way.' I just thought of me going to dinner or lunch with my girlfriends. I am not going to wear a frickin ballgown in the Bahamas. She was right in the sense it was work. It's whatever image each women wants to put out there of themselves. It's how they want to be perceived. I don't know a lot of them outside the show, so for me, that's why I said to the producers involved in the show, 'I can be myself or I can be the actress Denise Richards and be glammed up the whole time and be treated like I am filming a scripted show, playing a part,'" she stated on Bethenny Frankel's podcast, "Just B with Bethenny Frankel."
