Brandi Glanville -- Says Truth is a Defense vs. Joanna Krupa in Smelly Vagina Lawsuit

Brandi Glanville may have figured out a way to stave off Joanna Krupa's defamation lawsuit ... by forcing Joanna to come clean about her vaginal odor.

Brandi's lawyer has fired off a series of written questions which Joanna must answer under oath, notably:

It would seem Brandi and her attorney are going down a path that could lead to some interesting courtroom testimony ... and demonstrations.
