Usher Wife I Don't Buy STD Lawsuit Claims Against My Husband

 

 Usher and his wife, Grace Miguel, are rock solid on the heels of the $20 million lawsuit against him for allegedly giving a woman herpes ... TMZ has learned.

Sources close to the couple tell TMZ ... Grace isn't concerned at all about the allegation Usher slept with a woman, who sued as Jane Doe, at least twice this year. We're told Grace, who's been Mrs. Ush for 2 years, isn't giving the lawsuit any weight.

Our sources say the woman suing has a history with Usher. She was a close friend of his first wife, Tameka Harris, and attended their 2007 wedding. We're told Usher believes she has a thing against him, and has for a long time. That's why Grace is paying her no mind.

As we first reported ... the woman wants $20 mil from Usher for allegedly giving her herpes.
