It all took place when fans on Twitter wrote about who they would like to see on Watch What Happens Live and one person suggested Brandi and Kyle Richards as guests with Lisa as the bartender.
“As if Lisa would ever stand behind the bar. She doesn't play that game,” mystilettolife wrote and Brandi quickly responded with a slam against her co-star.
“Ummmm u don't know her yet she plays more games than my children.”
Fans immediately criticized Brandi for her acidic response, with @LRoz11 writing: “@hat a sh*tty tweet to post about @LisaVanderpump! Brandi, love, put down the bottle of wine & step away from the iPad!”
