Richards decided not to join the rest of her The Real Housewives of Beverly Hills castmates at the taping of Wednesday's episode of TheEllen DeGeneres Show because Bravo's January 20 broadcast of the reality series' season finale -- which revealed Richards' alleged alcoholism on national television -- humiliated her, RadarOnline reported Tuesday.
"She's not doing Ellen because Bravo aired that she was an alcoholic on the reality show and she didn't want that to be made public," the source said.
Richards reportedly cannot come to grips with her excessive drinking habits, which is why sobering up may be so difficult for her.
"She's not willing to admit she's an alcoholic. That's why she left rehab after one week," the source explained.
