The 27-year-old basketball star - who split with ex-wife Kim Kardashian in October after just 72 days of marriage - is beingsued for sexual battery by Kayla Goldberg, who alleges the sportsman gave her the sexually transmitted disease after they met up in August 2010.
According to the lawsuit, Kayla claims she met Kris in The Newsroom Cafe in Los Angeles and the pair went on to have unprotected sex in his room at the Thompson Hotel.
She is suing for unspecified damages, alleging that Kris knew he had the disease when they got together but didn`t tell her.
But the basketball star has denied such allegations saying he has "never" given anyone herpes, and he is now said to be thinking about counter-suing Kayla following her claims.
A source close to the NBA star told RadarOnline: "Kris was recently accused by another woman of giving her Herpes, this happened within the last two months.
"Kris tested negative for it though and for any other sexually transmitted disease and he is absolutely steadfast that he has never given anyone herpes. Kris plans on vigorously fighting the lawsuit filed against him by Kayla Goldberg and is considering counter-suing her for defamation."
