And her explanation was quite simple and to the point.
"Cause I'm not a Beverly Hills wife," Lancaster stated, which drew applause from the audience.
She continued, "I'm from England, as you all probably know, and I consider myself a very down-to-earth, girl next door, so I just wouldn't fit into that."
This casting news comes soon after Rinna slammed rumors that she would be appearing on the reality series, telling E! News, "Basically that was never gonna happen. It was interesting to watch happen without my knowledge." It was also recently revealed that last season's newbie, Marisa Zanuck, was not asked back.
Which means the hunt for the new housewives continues...
