"I watched #RHOBH last night," reads Denise's post. "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?"
Denise's statements could be in regards to several things, as the Oct. 19 episode touched upon lots of Lisa's season 12 drama, from host Andy Cohen calling out her social media behavior, to Lisa and Sutton Stracke reconciling their Elton John Gala beef, to the revelation that Lisa was the one who threw out Garcelle Beauvais' book, not Erika Jayne.
Things got emotional for Lisa while talking about the death of her mother, Lois Rinna, who passed away in Nov. 2021. The 59-year-old apologized for how the loss affected her actions and decision-making this season.
Denise and Lisa share drama of their own. During her two-season stint on the series, Denise had a falling out with Lisa over a rumor she had slept with RHOBH alum Brandi Glanville, which Denise denied. But Denise's beef with Lisa isn't something that would prevent her potential return to the series.
"I would be fine working with Lisa and filming with her," Denise—who starred on seasons nine and 10 of the reality series—told SiriusXM's Jeff Lewis on Sept. 1. "I never said I wouldn't go back because of her."
The third and final part of The Real Housewives of Beverly Hills season 12 reunion airs Wednesday, Oct. 26, at 8 p.m. on Bravo.
