Lisa Rinna revealed that she was allegedly drugged with fentanyl at the “Traitors” Season 4 premiere party last month.

During an appearance on “Good Day New York” Thursday morning to discuss her newly released memoir, “You Better Believe I’m Gonna Talk About It,” the “Real Housewives of Beverly Hills” star confirmed she got tested and the results showed she “had fentanyl in [her] system.”

“I’m not kidding. I had fentanyl, high levels of amphetamines and other things,” she confessed.

“But I can’t talk a lot about it because we’re still dealing with it. It was leaked and my team is dealing with it now,” Rinna, 62, said.

While the Bravo star declined to say who she believed drugged her, she claimed the incident took place “at The Abbey in West Hollywood.”

“Luckily, my husband [Harry Hamlin] was there and able to get me out of there quickly,” she shared.

Rinna also claimed that “so many people” she knows, including her daughter’s friends, claimed they were also drugged while partying at The Abbey.

“This is not a first-time thing,” she declared. “This is something that’s gone on for years and I do think it needs to be a conversation. I’m glad now that it’s out and we will deal with it.”

Page Six has reached out to The Abbey for comment but did not immediately hear back.

Earlier this week, sources told TMZ that Rinna’s “Traitors” co-star Colton Underwood became concerned when he noticed the Bravolebrity was “completely inebriated” at the party — although she hadn’t had that much to drink.

The outlet also reported that the “Bachelorette” alum, 34, helped Rinna through a group photo after noticing something wrong with her.

Underwood, who has been at odds with the “Dancing With the Stars” alum on the hit Peacock show, notified Rinna’s team and they quickly took her out of the festivities.
