Another Hollywood cat fight!  Rihanna and Tila Tequila are publicly taking jabs at each other!  Tila says Rihanna has HERPES!

Rihanna was a guest on “Big Boi’s Neighborhood Morning Show” on Thursday and used the opportunity to lash out at Tila Tequila!

The ‘Hard’ singer said:

“I don’t like when people talk about me and don’t know me and don’t know what they’re sayin’ and sound stupid. I saw her backstage at the AMA’s one year… [laughs] She was just standing there with a drink in her hand, even though she doesn’t drink she had a drink in her hand, whatever.”

Miss Tequila IMMEDIATELY took to her official blog to retaliate!  Tila went as far as saying that Rihanna has herpes!  She posted:

“So I woke up early this morning because I have to get ready to pack to catch an early flight out of town , and I get a google alert with my name with Rihanna!” she began. “So of course, I was interested on what the hell would Rihanna have to say about ME??? ME?? Really Rihanna????? Ok…but anyway before I actually read what she had to say about me, my first reaction was, “Awww, how cool! Rihanna is talking about me! She must be talking about how more women who have been in Domestic Violence cases should really support one another!”

“SO after I listened to Rihanna bad mouthing me, my first reaction was “WOW! WHAT A BITCH! AND A TOTAL LIAR! WOWWWW!”

“So everyone, yes…..I heard from legit sources, that is the HUGE SECRET our prestine, perfect little Princess RiRi, the “IDOL” has been hiding from the media. A very close source of mine, who works in the same legal camp as Rihanna, has told me that the reason why Rihanna wasn’t speaking out about the CHRIS BROWN incident is because there was a catch 22 in it. Rihanna has herpes, and… well… I don’t wanna put anyone else on blast, but Rihanna has herpes and gave someone else herpes that she had slept with.”
