Model-turned-reality Tv star Joanna Krupa has sued actor Eddie Cibrian's ex-wife over comments she made about her genitals.

Brandi Glanville upset her fellow Real Housewives star during an appearance on late-night U.S. chat show Watch What Happens Live when she claimed Krupa suffers from a vagina odour issue.

Krupa immediately threatened legal action and now it seems she has followed through by filing legal documents.

According to the papers, obtained by Tmz.com, Krupa experienced severe emotional distress as a result of Glanville's remarks, and she's suing her fellow reality Tv star for defamation.
