"The idea of discussing her divorce on national television, and being attacked by Brandi Glanville, Lisa Vanderpump and Yolanda Foster has Adrienne thinking twice about whether or not she will go to the taping of the reunion on Friday night," a source told RadarOnline.com exclusively.
"Even though Adrienne is contractually obligated to go, her lawyers have told her she doesn't have to because Bravo breached the contract by revealing details of the surrogacy of her twin sons. If Adrienne thought it would be a healthy environment, she wouldn't be considering not going.
"But look at past reunion shows of all the Housewives franchises...the women have made threats against each other, physical fights have almost broken out; host Andy Cohen was shoved by Teresa Giudice during a New Jersey Housewives reunion taping!"
Adrienne's estranged husband, plastic surgeon, Dr. Paul Nassif won't be attending the reunion, but taped a brief interview that will air.
"Paul is out of the country and unable to attend the reunion, but he did sit down for an interview that will be a part of it. He just wanted to let the fans know how he was doing, and wanted to thank everyone for their support during the divorce proceedings," the insider revealed.
Brandi and Adrienne have been viciously fighting all season, including one battle that threatened to turn REALLY nasty and end up in court after Brandi gossiped about a Maloof family secret. Meanwhile, Adrienne has accused Brandi of cozying up to Nassif and of having ulterior motives for doing so.
As RadarOnline.com previously reported, Bravo executives will likely ax a majority of the cast of the Real Housewives of Beverly Hills to shake things up in the 90210.
The only cast members guaranteed to come back for the fourth season of the smash hit reality franchise are Brandi and Lisa.
