Usher finally responds to Herpes lawsuit,wants it dismissed

A month after news broke that Usher allegedly gave an unidentified Georgia woman the herpes virus,he's now fighting back.

The singer has responded to the $20 million lawsuit filed by a Georgia woman who claims he gave her genital herpes back in April.

In Usher's legal docs, obtained by TMZ, he notes her lawsuit says nothing about whether she had been tested prior to their alleged sexual encounter. He says, "A previous sexual partner very well may have already infected her."

And, Usher says, she could have contracted the STD after their alleged encounter.
And he also says she assumed the risk of getting herpes by having "casual, unprotected sexual intercourse and/or oral sex."

However,Usher did not attack the lawsuit by saying he couldn't have given her herpes.
 His lawyer also says there's no cause for the woman to secretly file her lawsuit.
He's asking the judge to throw out her lawsuit.
