AceShowbiz - R&B singer Usher has asked a judge to seal the legal documents in his herpes lawsuit. The "Yeah!" star is facing court action from Quantasia Sharpton, who went public with her rumoured night of passion with Usher during a press conference in August 2017.

Sharpton revealed she had not contracted herpes from the alleged encounter at a Days Inn hotel following an Usher concert in Atlantic City, New Jersey in 2014, but is suing because she believes she had been put at risk by the musician.

Usher has refuted her claims and according to Bossip.com, the singer is now seeking to keep his responses to her requests for evidence under wraps. He is reportedly worried his answers will identify another unnamed woman suing him for the same reason and expose her medical records, while he is also concerned private information could be made public in the media and violate a reported court order between himself, Sharpton and the unidentified woman.

A hearing on the motion is scheduled for later this month.

The unidentified Georgia woman, who claims she was diagnosed with herpes after sleeping with the musician, filed suit in July 2017, demanding $20 million in punitive damages and another $20 million for emotional harm and medical bills.

Usher, who recently separated from his second wife Grace Miguel, has also denied those allegations and previously asked a judge to dismiss the lawsuit.
