Her former husband David Gest announced in 2006 that Liza knew that she had Genital Herpes and did not tell him until six months after they were married and one year after they began seeing each other.
Minnelli fired back saying that she lived in constant fear while married to Gest because he was trying to poison her with drugs.
The couple got married in March of 2002 is a lavish ceremony where Gest's long time friend Michael Jackson was the best man. Failing to tell Gest about having Herpes before the ceremony would be considered fraud under the couple's prenuptial agreement allowing Gest to go after half of Minnelli's assets.
Minnelli is best known for her 1972 Academy Award winning performance in Cabaret.
David Gest's produced "Michael Jackson: 30th Anniversary Celebration" the highest rated musical special in television history.
