Talib Kweli Greene has been accused of sexual harassment by his former collaborator, the singer Shareese Ballard. Ballard, who records under the name Res, worked with Greene in the duo Idle Warship. As a solo artist, she was signed to Greene’s record label Javotti Media. Res has also appeared on multiple Talib Kweli solo records. On Friday, Ballard posted multiple tweets accusing the rapper of refusing to release music she gave him years ago, bullying her, and taking her career “hostage.” Their social media feud then revealed an ongoing legal battle between the two artists.

She then claimed Greene did all of these things because she rejected his advances. She shared a screenshot of an alleged 2014 email from Greene, which shows the rapper admitting to trying to kiss her once. She also claimed that there are other women with stories about the rapper.

Greene responded by sharing a statement that accompanied a screenshot of a court document, which confirmed the legal battle between the two. After calling her a liar, he said she was dropped from his label in 2013 “for disrespecting my employees and for failing to turn in an album I invested in.” He added, “I fully and categorically deny any allegation of sexual harassment.”

According to court documents obtained by Pitchfork, Greene and Javotti Media sued Ballard in 2016 for breach of contract and a copyright violation. The lawsuit claims that Ballard was paid over $20,000 in advances for new recordings, “continually failed to show up for obligations,” and didn’t deliver an album. The complaint then notes that Res then launched an Indiegogo campaign to raise money for her new album in early 2016, and as a reward, offered the song “You Don’t Know Me” featuring Talib Kweli. The rapper sent a cease and desist letter over the song’s release, which he then claims was ignored. In his Instagram statement, Greene said the Indiegogo incident prompted the lawsuit.

In September 2016, Ballard filed a counterclaim, which states that she provided Javotti Media with the album. She also countersued Greene for sexual harassment. “During the course of the parties' collaboration on at least two occasions, Mr. Greene made unwanted and unprovoked sexual advances toward Ms. Ballard,” the counterclaim reads. “These unwanted and unprovoked sexual advances by Mr. Greene toward Ms. Ballard made Ms. Ballard feel uncomfortable and demeaned.”
