It's time for another The Real Housewives of Beverly Hills
reunion – but this time, one important cast member will be missing.
Host Andy Cohen starts off the reunion by announcing Maloof's departure
from the reality series, "Today we are missing one of the Housewives who has been with us since the beginning. Adrienne Maloof has decided not to participate today," he explains. (Watch the video below.)
"This season was hard on Adrienne
– as you know all know – a secret about her family was revealed by Brandi [Glanville]
and from that moment on, Adrienne refused to speak directly about it ... Not only is she absent tonight, but she won't be on the show next season," Cohen continues.
But Maloof's failure to appear on the reunion show isn't the biggest shocker.
In a preview clip of the two-part show, there are plenty of tears and even more accusations.
"That is the meanest thing you can say," Kyle Richards
says to Glanville, sobbing.
"Why don't you say what you said about Lisa [Vanderpump]
in Paris?" Richards asks Yolanda Foster, who looks stunned.
Part one of the reunion airs March 25 on Bravo.
