The Real Housewives of Beverly Hills star Lisa Vanderpump has vehemently denied accusations that she sold a story about Dorit Kemsley to Radar Online both on and off-screen.
Tuesday's episode of the Bravo hit chronicled Lisa's plight to have scientific proof that she was telling the truth.
The episode kicked off with her and John Sessa making their way to a polygraph examiner's office.
The examiner was named John. Yes, there's another John on this reality TV series.
