Kris Humphries has just been sued by a woman who claims he gave her herpes ... TMZ has learned.
Kayla Goldberg claims she met Kris in August, 2010 at the Newsroom Cafe on Robertson Blvd in L.A. -- long before Kris met Kim Kardashian. The two flirted, exchanged numbers, and Kayla claims that night they met up at Trousdale nightclub on the Sunset Strip.
According to the suit, Kris came on to Kayla, touching, kissing and dancing with her. Kayla claims he took her to his hotel and they had sex multiple times ... including oral sex. The suit claims during a portion of the sexual encounter Kris did not wear a condom.
The lawsuit claims Kris did not inform Kayla he had herpes -- and she claims in the suit that he did indeed have the disease.
Kayla says a week later she was diagnosed with herpes. Her symptoms included a sore throat, fever, body aches and immobilizing pain, as well as extreme vaginal irritation and painful lesions on her genitalia.
She's suing for sexual battery claiming Kris knew he had herpes when they hooked up and didn't tell her.
Kayla -- who put her full name in the lawsuit -- is suing for unspecified damages.
We reached out to Kris for comment ... so far no response.
