Two women and a man are accusing Usher of not telling them he had herpes, according to a lawsuit filed Monday.
Attorney Lisa Bloom announced the suit during a press conference with one of the accusers.
The accuser alleged she had sexual contact with Usher at a hotel room when she was 19 years old. She said the singer did not warn her about the STD.
"We engaged in sexual contact," Quantasia Sharpton said at the press conference in New York City. "He never warned me about any STDs."
A rep for Usher has not yet returned Fox News' request for comment.
