"The Real Housewives of Beverly Hills" cast is expected to bring the drama. Surprisingly though, it's two former cast members who have kept the pot stirring recently: Lisa Vanderpump and Eileen Davidson. 

It all started when Eileen appeared on "Watch What Happens Live with Andy Cohen." The 60-year-old played a little game called "Spill on the Hills" in which Cohen asked her opinion on a series of hot topics regarding the Beverly Hills franchise. All was fine and dandy until a question about Vanderpump's decision to skip the Season 9 reunion and quit the show.  

"[Expletive] move," the soap opera star replied. 

It didn't take too long for word to get back to Lisa and when it did, she clapped back at the former housewife on social media. 

"Mmm @eileen_davidson At least I resigned, you weren’t honest about the fact that you were fired," the 59-year-old tweeted. "Now that’s a [expletive] move as you call it."

Eileen wasn't the only one who shaded the former "RHOBH" veteran. Wendy Williams didn't hold back her thoughts when she appeared on "WWHL" earlier this month, which happened to boil down to just one word: "replaceable."

Lisa appeared unbothered by "The Wendy Williams Show" host. A source revealed to HollywoodLife that the British restauranteur was "too busy and focused" to care what Willams thinks of her. 

"The Real Housewives of Beverly Hills" Season 10 is set to premiere in 2020.
