A former executive at the dating site Tinder sued the company and its former CEO on Monday alleging he sexually assaulted her and the company fired her in retaliation for her complaint.

Rosette Pambakian said in the lawsuit filed in Los Angeles Superior Court that former Match Group and Tinder CEO Gregory Blatt made a lewd overture to her at a company holiday party in 2016 at the SLS Hotel in Beverly Hills.

Pambakian said she went with two work friends to a hotel room upstairs to get away from Blatt, but he later showed up and groped and kissed her without consent. She said her two colleagues, including Blatt’s executive assistant, witnessed the encounter.

The company owned by IAC/InterActiveCorp, which is controlled by media mogul Barry Diller, conducted a sham investigation that concluded the behavior was “consensual cuddling,” her lawyers said.

The Match Group denied Pambakian was fired as retaliation for reporting Blatt and said an independent investigation found there was no violation of law or company policy, according to a statement from its board.

Pambakian and other Tinder executives sued Match and IAC seeking $2 billion a year ago for allegedly bilking them by manipulating financial information to create a lowball estimate of Tinder’s value.

That lawsuit included Pambakian’s sexual misconduct allegations. At the time, the company said that lawsuit was meritless.
