"Kim believes that Brandi is an alcoholic and needs to get help,” the production insider revealed to RadarOnline.com.
"Producers of The Real Housewives of Beverly Hills wanted to stage an intervention for Brandi that would have aired on the fourth series of the Bravo show.”
But after Glanville, 41, found out about the planned intervention, "she shot it down… immediately!”
Said the source: "Brandi didn't want to be a part of it and insisted she doesn't have a drinking problem… she didn't want her kids to see it (either).”
Said a second source: “Producers had pitched for Kim or Lisa to do the intervention, but Brandi refused… she felt Kim doing it would be 'the blind leading the blind' because of her own past issues."
The failed intervention plan followed the infamous incident in July when the reality star partied, stumbled and lost part of her dress during a boozy night out in Hollywood.
Since, she’s been snapped wasted again — this time, at the weekend, leaving Fleming’s Prime Steak House & Wine Bar in Beverly Hills where she celebrated her birthday with friends.
In an email to VH1 Gossip Table host Rob Shuter on Monday, Glanville blasted rumors that “friends” were concerned about her ongoing behavior.
She wrote: "Omg so dumb! No one is worried we had a fun night yes we all had bday shots and a great time we left flemings in bh to a sea of flash bulbs and then we went and danced our butts off.”
But RadarOnline.com can reveal those friends included all members of the RHOBH cast, including Kyle Richards, Lisa Vanderpump, Yolanda Foster and Joyce Giraud, but not Carlton Gebbia, who our source noted has "become very good friends with Brandi.”
