In addition to Diaz, the lawsuit names Merkley+Partners and its parent company Omnicom Group as defendants.
Merkley+Partners is a 30-year-old full-service ad firm that has created campaigns for brands including Mercedes-Benz, White Castle, and Florida's Natural.
"You went down on me, I went down on you, we had sex," the lawsuit says Diaz told the plaintiff.
The lawsuit also says O'Rear was "treated in a cruel and callous fashion" during the firm's investigation.
O'Rear's attorney told BI she was no longer working at the ad agency but declined to comment further.
